My little project - extension for Firefox that translate text. User select text on page, make right click and see translation right in the context-menu or in popup. In my contextMenu.Item I am using context: contextMenu.SelectionContext() for determin context (for example, user click on image or on selected text).
But this not working if text selected in input field, documentation page not mentioned it. What I need to do for handling selection context for input fields, not only for regular text on page? In this situation I see my context-menu, but in debug I see that selected text was not send to the code of my extension.
I tried this code - nothing.
My current code is:
const { getMostRecentBrowserWindow } = require('sdk/window/utils');
var uuid = require('sdk/util/uuid').uuid();
var uuidstr = uuid.number.substring(1, 37);
var notifications = require("sdk/notifications");
var contextMenu = require("sdk/context-menu");
var Request = require("sdk/request").Request;
var self = require('sdk/self');
var tabs = require('sdk/tabs');
var prefs = require('sdk/simple-prefs').prefs;
var cmitems = null;
var wasTranslatedSecondTime = false;
var inProgress = '...';
var translated = '';
var menuItem = contextMenu.Item({
data: uuidstr, // for 'binding' tooltop's 'id' + text
label: inProgress, // ...
image: self.data.url('ico.png'),
context: contextMenu.SelectionContext(),
contentScript: 'self.on("context", function() {' +
'var selectionText = window.getSelection().toString();' +
'self.postMessage({name:"context", data:selectionText});' +
'return true;' +
'});' +
'self.on("click", function() {' +
'var selectionText = window.getSelection().toString();' +
'self.postMessage({name:"click", data:"https://translate.yandex.ru?text=" + selectionText.replace("&", "%26")});' +
'})',
onMessage: function(message) {
if (message.name == 'context') {
menuItem.label = inProgress; // ...
if (cmitems != undefined) cmitems[0].tooltipText = '';
var input = message.data.replace('&', '%26');
translate('ru', input); // default direction - from EN to RU
} else { // if (message.name == 'click')
tabs.open(message.data);
}
}
});
function translate(lang, input) {
Request({ // key is not referral but API-key: https://api.yandex.com/translate/doc/dg/concepts/api-overview.xml
url: 'https://translate.yandex.net/api/v1.5/tr.json/translate?key=trnsl.1.1.20150627T071448Z.117dacaac1e63b79.6b1b4bb84635161fcd400dace9fb2220d6f344ef&lang=' +
lang + '&text=' + input,
onComplete: function (response) {
translated = response.json.text[0];
if (input == translated && wasTranslatedSecondTime == false) { // if input on Russian and we receive the same text -
translate('en', input); // translate again selected text into English
wasTranslatedSecondTime = true;
} else { // show results
if (prefs.popup) popup(translated);
menuItem.label = translated;
wasTranslatedSecondTime = false;
if (prefs.tooltip) tooltip(translated);
}
}
}).get();
}
function popup(text) {
if (text.length > 0)
notifications.notify({
title: 'translate.yandex.ru',
text: text,
time: 5000
})
}
function tooltip(translated) {
menuItem.data = uuidstr + translated;
cmitems = getMostRecentBrowserWindow().document.querySelectorAll(".addon-context-menu-item[value^='"+uuidstr+"']");
cmitems[0].tooltipText = cmitems[0].value.substring(36);
}
It appears that your question boils down to: How do I get the selected text, even when it is in an input field?
You are currently using var selectionText = window.getSelection().toString(); which is failing when the selected text is in an input field.
In one of my extensions, I use the following to obtain the selected text. It works even when the selected text is in an input field:
/**
* Fix an issue with Firefox that it does not return the text from a selection if
* the selected text is in an INPUT/textbox.
*/
function getSelectedText(win,doc) {
//Adapted from a post by jscher2000 at:
// http://forums.mozillazine.org/viewtopic.php?f=25&t=2268557
//Is supposed to solve the issue of Firefox not getting the text of a selection when
// it is in a textarea/input/textbox.
var ta;
if (win.getSelection && doc.activeElement){
if (doc.activeElement.nodeName == "TEXTAREA" ||
(doc.activeElement.nodeName == "INPUT" &&
doc.activeElement.getAttribute("type").toLowerCase() == "text")
){
ta = doc.activeElement;
return ta.value.substring(ta.selectionStart, ta.selectionEnd);
} else {
//As of Firefox 31.0 this appears to have changed, again.
//Try multiple methods to cover bases with different versions of Firefox.
let returnValue = "";
if (typeof win.getSelection === "function"){
returnValue = win.getSelection().toString();
if(typeof returnValue === "string" && returnValue.length >0) {
return returnValue
}
} //else
if (typeof doc.getSelection === "function"){
returnValue = doc.getSelection().toString();
if(typeof returnValue === "string" && returnValue.length >0) {
return returnValue
}
} //else
if (typeof win.content.getSelection === "function"){
returnValue = win.content.getSelection().toString();
if(typeof returnValue === "string" && returnValue.length >0) {
return returnValue
}
} //else
//It appears we did not find any selected text.
return "";
}
} else {
return doc.getSelection().toString();
}
}

Here on this text box i have attached changed event though jQuery. The requirement is that whenever the criteria changes the treeview div will be filled with data will be refreshed.
AssignPayReportsToDeposit.AttachEvents = function () {
$("#ddSupplier").change(AssignPayReportsToDeposit.OnSupplierChange);
$("#ddLastMonth").change(AssignPayReportsToDeposit.OnLastMonthChange);
$("#txtMonths").change(AssignPayReportsToDeposit.OnMonthsChange);
}
these changed event handler will handle the refreshing the treeview. The whole thing is handled through ajax calls.
Now i know that using Ajax.ActionLink and UpdateTargetId parameter with Replace option i can return the treeview in partial view so the manual handling can be removed. but that will require me put the anchor button which user have to click. Requirement is that the refresh of treeview should be done on any criteria change.
Is there any way i am able to achieve this using Ajax.ActionLink (or any another razor syntax that will take load off from the manual handling ) ? On change event of the controls i would like to call a controller using ajax.actionlink which will return a partialview and update the div.
Edit: I am handling this through jQuery right now. so i will post the complete code for more understanding.

JavaScript File (the code is a bit lengthy so you don't need to look at all of them you can see the methods which are calling the action methods. GetUnAssignedPayReports and GetAssignedPayReports which returns the data which is used to fill the tree view.) I just want this portion to moved to partial view and passing model to partial view generate treeview there and replace the div each time on change event with rendering partial view again. Hope i am clear enough. so change the above methods to return partial instead of json result that what i am trying to achive

Unfortunately not out the box.
The Ajax extension methods are really just HTML helpers that work with other jQuery libraries. The helpers create the relavant HTML markup (such as adding custom addtributes data-*="") and the client scripts use this to determine their behaviour.
You could create your own MVC HTML helper and script library to handle change events for you however I would recommend looking at a front end framework such as Angular instead. This library would handle all the events declaratively so you don't need to waste time writing event handlers.
Inside my ion-content I have a list which when scrolled to the bottom more items are loaded (provided by ion-infinite-scroll which calls 'LoadMore()').
The problem is that if I set direction = xy to ion-content, ion-infinite-scroll calls 'LoadMore()' if I scroll vertically and horizontally.
It is possible to my ion-infinite-scroll only call 'LoadMore()' when scrolled vertically?
Currently ionic version beta.13 does not support this feature.
I already have posted my suggested solution on ionic repository ( https://github.com/driftyco/ionic/issues/1073 )
I've created 'ion-infinite-scroll-fixed' directive wich differs only in last if block:
.directive('ionInfiniteScrollFixed', ['$timeout', function($timeout) {
function calculateMaxValue(distance, maximum, isPercent) {
return isPercent ?
maximum * (1 - parseFloat(distance,10) / 100) :
maximum - parseFloat(distance, 10);
}
return {
restrict: 'E',
require: ['^$ionicScroll', 'ionInfiniteScrollFixed'],
template: '<i class="icon {{icon()}} icon-refreshing"></i>',
scope: true,
controller: ['$scope', '$attrs', function($scope, $attrs) {
this.isLoading = false;
this.scrollView = null; //given by link function
this.getMaxScroll = function() {
var distance = ($attrs.distance || '2.5%').trim();
var isPercent = distance.indexOf('%') !== -1;
var maxValues = this.scrollView.getScrollMax();
return {
left: this.scrollView.options.scrollingX ?
calculateMaxValue(distance, maxValues.left, isPercent) :
-1,
top: this.scrollView.options.scrollingY ?
calculateMaxValue(distance, maxValues.top, isPercent) :
-1
};
};
}],
link: function($scope, $element, $attrs, ctrls) {
var scrollCtrl = ctrls[0];
var infiniteScrollCtrl = ctrls[1];
var scrollView = infiniteScrollCtrl.scrollView = scrollCtrl.scrollView;
$scope.icon = function() {
return angular.isDefined($attrs.icon) ? $attrs.icon : 'ion-loading-d';
};
var onInfinite = function() {
$element[0].classList.add('active');
infiniteScrollCtrl.isLoading = true;
$scope.$parent && $scope.$parent.$apply($attrs.onInfinite || '');
};
var finishInfiniteScroll = function() {
$element[0].classList.remove('active');
$timeout(function() {
scrollView.resize();
checkBounds();
}, 0, false);
infiniteScrollCtrl.isLoading = false;
};
$scope.$on('scroll.infiniteScrollComplete', function() {
finishInfiniteScroll();
});
$scope.$on('$destroy', function() {
void 0;
if(scrollCtrl && scrollCtrl.$element)scrollCtrl.$element.off('scroll', checkBounds);
});
var checkBounds = ionic.animationFrameThrottle(checkInfiniteBounds);
//Check bounds on start, after scrollView is fully rendered
setTimeout(checkBounds);
scrollCtrl.$element.on('scroll', checkBounds);
function checkInfiniteBounds() {
if (infiniteScrollCtrl.isLoading) return;
var scrollValues = scrollView.getValues();
var maxScroll = infiniteScrollCtrl.getMaxScroll();
if ((maxScroll.left !== -1 && scrollValues.left >= maxScroll.left && $attrs.notOnHorizontal !=="true") ||
(maxScroll.top !== -1 && scrollValues.top >= maxScroll.top && $attrs.notOnVertical !=="true")) {
onInfinite();
}
}
}
};
}]);
and in my HTML:
<ion-infinite-scroll-fixed
not-on-horizontal="true"
ng-if="infiniteScroll.canLoad"
on-infinite="infiniteScroll.loadMore();"
distance="1%">
</ion-infinite-scroll-fixed>
I hope this can help somebody :)
I have the below jquery scrip on my website which works fine. I wanted to make the menu fixed on top, due to which now a part of the text gets hidden behind the fixed menu. how can i make the smooth scroll script to stop at 160px; from the .top of the browser
Thanks for any help in advance.
Cheers.
<script type="text/javascript">
$(document).ready(function() {
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top;
$(this).click(function(event) {
event.preventDefault();
$(scrollElem).animate({scrollTop: targetOffset}, 1000, function() {
location.hash = target;
});
});
}
}
});
// use the first element that is "scrollable"
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
return [];
}
});
</script>
EDIT 2: I tried to play around with the script and i added a scrolloffset and a preventdefault() condition. It works when i click a link the first time a page is loaded. If i click on any other link again, it doesnt scroll at all.
var scrollOffset = 160;
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top - scrollOffset;
$(this).click(function(event) {
if(event != 'undefined') {
event.preventDefault();}
$(scrollElem).animate({scrollTop: targetOffset}, 1000, function(e) {
e.preventDefault();
location.hash = target;
I'm not sure if it works but try to just add "+ 160" to the scroll-target.
Remove location.hash since it scrolls back to the target element.
Toggle button in jqgrid top toolbar is defined using Oleg answer as
var autoedit;
$("#grid_toppager_left table.navtable tbody tr").append(
'<td class="ui-pg-button ui-corner-all" >' +
'<div class="ui-pg-div my-nav-checkbox">' +
'<input tabindex="-1" type="checkbox" id="AutoEdit" '+(autoedit ? 'checked ' : '')+'/>' +
'<label title="Toggle autoedit" for="AutoEdit">this text is ignored in toolbar</label></div></td>'
);
$("#AutoEdit").button({
text: false,
icons: {primary: "ui-icon-star"}
}).click(function () {
autoedit = $(this).is(':checked');
});
Answer from how to add standard textbox command to jqgrid context menu is used to autogenerate context menu for grid from toolbar.
In generated context menu for this item only text "this text is ignored in toolbar" appears and selecting it does nothing.
How to make it work or remove this item from context menu?
Look at the demo or the same demo with another themes: this and this.
First of all I modified the code of the jquery.contextmenu.js to support jQuery UI Themes. Then I modified the code more, to be able to create context menu more dynamically. In the modified version of jquery.contextmenu.js one can crate menu and the bindings not only in the onContextMenu, but also in onShowMenu. Inside of onContextMenu one can create just the empty menu
<div id="myMenu"><ul></ul></div>
It is important only if one use dynamically switching of the icons of the text of buttons from the navigator bar.
You can download the modified version of the file here.
In the demo I used the last modification of the code from the answer, so the standard context menu can be still used in the grid on selected text or in the enabled input/textarea fields. The context menu of the browser will be displayed in the case:
I modified the code of createContexMenuFromNavigatorButtons function from the answer to the following:
var getSelectedText = function () {
var text = '';
if (window.getSelection) {
text = window.getSelection();
} else if (document.getSelection) {
text = document.getSelection();
} else if (document.selection) {
text = document.selection.createRange().text;
}
return typeof (text) === 'string' ? text : text.toString();
},
createContexMenuFromNavigatorButtons = function (grid, pager) {
var menuId = 'menu_' + grid[0].id, menuUl = $('<ul>'),
menuDiv = $('<div>').attr('id', menuId);
menuUl.appendTo(menuDiv);
menuDiv.appendTo('body');
grid.contextMenu(menuId, {
bindings: {}, // the bindings will be created in the onShowMenu
onContextMenu: function (e) {
var p = grid[0].p, i, lastSelId, $target = $(e.target),
rowId = $target.closest("tr.jqgrow").attr("id"),
isInput = $target.is(':text:enabled') ||
$target.is('input[type=textarea]:enabled') ||
$target.is('textarea:enabled');
if (rowId && !isInput && getSelectedText() === '') {
i = $.inArray(rowId, p.selarrrow);
if (p.selrow !== rowId && i < 0) {
// prevent the row from be unselected
// the implementation is for "multiselect:false" which we use,
// but one can easy modify the code for "multiselect:true"
grid.jqGrid('setSelection', rowId);
} else if (p.multiselect) {
// Edit will edit FIRST selected row.
// rowId is allready selected, but can be not the last selected.
// Se we swap rowId with the first element of the array p.selarrrow
lastSelId = p.selarrrow[p.selarrrow.length - 1];
if (i !== p.selarrrow.length - 1) {
p.selarrrow[p.selarrrow.length - 1] = rowId;
p.selarrrow[i] = lastSelId;
p.selrow = rowId;
}
}
return true;
} else {
return false; // no contex menu
}
},
onShowMenu: function (e, $menu) {
var options = this, $menuUl = $menu.find('ul:first').empty();
$('table.navtable .ui-pg-button', pager).each(function () {
var $spanIcon, text, $td, id, $li, $a, button,
$div = $(this).children('div.ui-pg-div:first'),
gridId = grid[0].id;
if ($div.length === 1) {
text = $div.text();
$td = $div.parent();
if (text === '') {
text = $td.attr('title');
}
if (this.id !== '' && text !== '') {
id = 'menuitem_' + this.id;
if (id.length > gridId.length + 2) {
id = id.substr(0, id.length - gridId.length - 1);
}
} else {
// for custom buttons
id = $.jgrid.randId();
}
$li = $('<li>').attr('id', id);
$spanIcon = $div.children('span.ui-icon');
if ($spanIcon.length > 0) {
// standard navGrid button or button added by navButtonAdd
$li.append($('<a>')
.text(text)
.prepend($spanIcon.clone().css({
float: 'left',
marginRight: '0.5em'
})));
$menuUl.append($li);
options.bindings[id] = (function ($button) {
return function () { $button.click(); };
}($div));
} else {
button = $div.children("input").data("button");
if (button !== undefined) {
$a = $('<a>')
.text(button.options.label)
.prepend(
$('<label>').addClass("ui-corner-all").css({
float: 'left',
width: '16px',
borderWidth: '0px',
marginRight: '0.5em'//'4px'
}).append(
$('<span>').addClass("ui-button-icon-primary ui-icon " +
button.options.icons.primary)
.css({
float: 'left',
marginRight: '0.5em'
})
)
);
$li.append($a);
if (button.type === "checkbox" && button.element.is(':checked')) {
$a.find('label:first').addClass("ui-state-active");
}
$menuUl.append($li);
options.bindings[id] = (function ($button, isCheckbox) {
if (isCheckbox) {
return function () {
if ($button.is(':checked')) {
$button.siblings('label').removeClass("ui-state-active");
} else {
$button.siblings('label').addClass("ui-state-active");
}
$button.click();
$button.button("refresh"); // needed for IE7-IE8
};
} else {
return function () { $button.click(); };
}
}(button.element, button.type === "checkbox"));
}
}
}
});
return $menu;
}
});
},
autoedit = false;
and fill the check-button in the navigator bar with the code which is changed only a little:
$("#pager_left table.navtable tbody tr").append(
'<td class="ui-pg-button ui-corner-all">' +
'<div class="ui-pg-div my-nav-checkbox">' +
'<input tabindex="-1" type="checkbox" id="AutoEdit" />' +
'<label title="Checkx caption which should appear as button tooltip"' +
' for="AutoEdit">Autoedit</label></div></td>'
);
$("#AutoEdit").button({
text: false,
icons: {primary: "ui-icon-mail-closed"}
}).click(function () {
var iconClass, $this = $(this);
if (!autoedit) { // $this.is(':checked')) {
autoedit = true;
iconClass = "ui-icon-mail-open";
} else {
autoedit = false;
iconClass = "ui-icon-mail-closed";
}
$this.button("option", {icons: {primary: iconClass}});
});
createContexMenuFromNavigatorButtons($grid, '#pager');
UPDATED: One more demo which support buttons added by new inlineNav method you can find here. Additionally I included in the demo the function normalizePagers which I use to improve the look of the pager:
How you can see the contextmenu includes only enabled buttons from the navigator bar.
