I have a dynamic google map on my site with some custom markers. What I need to do is, when I click a specific marker I want a div to load underneath the map with the information about that marker (a shop) using Ajax.
Thanks a mil for your help,
Joanne
You can bind event handler to your marker and execute ajax request to get marker information from server side script e.g. using jquery post.
Then on server side you can get necesswary info on the basis of some marker data like its position.
google.maps.event.addListener (marker, 'click', function(event) {
var position = marker.getPosition();
$.post("getmarkerdata.php",{
latitute: position.lat(),
longitude: position.lng()
}),
function(data){
$(yourdiv).html(data);
}
});

I haven't seen much documentation and cant seem to get my code to work. the code snippet is below. I'm trying to remove the on mouse over listener but have had no success. Google charts docs has the method as such - google.visualization.events.remove Listener(listener_handler).
I'm uncertain what the listener_handler actually pertains to. Im trying to remove the on mouse over listener once the chart has been clicked.
google.visualization.events.addListener(chart, 'onmouseover', chartMouseOver);
google.visualization.events.addListener(chart, 'onmouseout', chartMouseOut);
google.visualization.events.addListener(chart, 'select', function () {
google.visualization.events.removeListener(chartMouseOver);
}
You need to store the returned event object in a variable, and pass that to removeListener :
var event = google.visualization.events.addListener(chart, 'onmouseover', function() {
alert('onmouseover');
google.visualization.events.removeListener(event); //the event object as param
});

I am trying to scrape information from a specified website. This site uses authentication first, thus a i use zombie.js:
var Browser = require("zombie");
var browser = new Browser();
browser.visit("https://*****login.aspx", function(){
browser.fill('#user', '*****');
browser.fill('#pwd', '*****');
var button = browser.querySelector('#btnSubmit');
browser.fire('click', button, function(){
//scraping main.aspx
});
});
It's working, i can scrape the main.aspx: there is a <table>, containig information about new messages(from, date, subject,), the problems comes here: the subject field is clickable, and clicking on it makes a new window appear with the actual message. However it is an ajaxgrid, and when i perform a click:
var field = browser.querySelector('#VeryLongIdOfTheField');
browser.fire('click', field, function(){
console.log(browser.querySelector('#VeryLongIdOfTheFieldContainingTheMessage').innerHTML);
});
it returns an error message, saying that undefined has no innerHTML. I suppose its because this action handled with some ajax magic. I am new in this js/nodejs/jquery/.. world, some help needed to enlight me.
Since the data is populated using async ajax, I'm guessing there's a lag between your click and the actual DOM population inside the node. How about waiting for a bit before checking the content inside the node.
browser.fire('click', field, function(){
setTimeout(function(){
console.log(browser.querySelector('#VeryLongIdOfTheFieldContainingTheMessage').innerHTML);
}, 3000)
});
If the time taken is not very predictable, you could also run it inside a loop until you find the content or exit after a reasonable number of retries.
I am trying to implement CKEditor 4 into an ASP NET website that I am working on, but I cannot figure out how I would save the edited material from the inline editor I know how to do it with the the old version, but I just don't understand the process for this.
I have looked in the forums... There is not v4 forum.
I looked in for the documentation.... Couldn't find it.
I have a feeling that this is a simple task, but I just don't know how.
You can get your data with CKEDITOR.instances.editor1.getData(). Then you can send it via AJAX or store it as a value of some input field. To do this periodically, follow this method:
CKEDITOR.disableAutoInline = true;
var editor = CKEDITOR.inline( 'editable' );
var savedData, newData;
function saveEditorData() {
setTimeout( function() {
newData = editor.getData();
if ( newData !== savedData ) {
savedData = newData;
// Send it with jQuery Ajax
$.ajax({
url: 'yourUrl',
data: savedData
});
// Or store it anywhere...
// ...
// ...
}
saveEditorData();
}, 500 );
};
// Start observing the data.
saveEditorData();
You can also observe the submit event and update some (hidden) form field with your data.
Have fun!
Are you trying to get it with AJAX or send with a form? The value of for example the top right inline editor area with Lorem Ipsum can be gotten like in the older version with simply
CKEDITOR.instances.editor1.getData().
In the XHTML output example they have a simple form that seems to work and I believe that using an (static) inline editor is just the same.
If you transform elements into editors inline dynamically, I would try to bind to the submit event and before submitting loop through all CKEDITOR.instances, get their data into hidden from fields. As for the hidden field naming or identifying which hidden field corresponds to which dynamic editor you'll have to figure out yourself :)
So i I have a page that contains links that call an httpRequest. The request calls a php file that grabs data from mysql and pre populates a form which is then returned to the browser/webpage. My problem is that when the page is returned to the browser via the httpRequest/ajax the text area does not display the tinymce editor, it just displays a normal text area. It looks like my request and ajax is working fine the text area just doesn't have the tinycme editor on it.
When i don't use ajax it works fine but when i put it in a separate file and call it via ajax it doesn't bring in the tinymce editor.
Does anyone know how to fix this problem so that my ajax generated page displays the text area with the tinymce editor. Thank you.
Lets presume that your thinyMCE instance is initialized with code below
// initialize tinyMCE in page
tinyMCE.init({
mode: "textareas",
theme: "advanced"
});
and you have some kind of button somewhere in the page. For purpose of this tip, i will not give it any ID but you may. Now, using jQuery you can easily attach event handler to that button which will call through AJAX your server and take content which you want to put tinyMCE editor. Code which will do such job would look somehow like below.
$(function() {
$("button").bind("click", function() {
var ed = tinyMCE.get('content');
ed.setProgressState(1); // Show progress
$.getJSON('/page/12.json', { /* your data */
}, function(data) {
ed.setProgressState(0); // Hide progress
ed.setContent(data["body"]);
}
});
});
});
You can see that on button.click ajax will call url /page/12.json which will return JSON as response. bare minimum of that response could be:
{
title: "Page title",
body: "<html><head><title>Page title</title>......</html>"
}
I attached anonymous function as callback which will handle response from server. and hide progress indicator which is shown before ajax call.
About JSON
JSON is shorten of JavaScript Object Notation. It is JavaScript code!!! So don't be confused about it. Using JSON you can make javascript object which can have attributes you can use later in your code to access particular peace of data which that object "holds". You can look at it as some kind of data structure if it is easier to you.
Anyway, to show you how this JSON can be created by hand look at examples below
var data = new Object();
data.title = "Page title";
data.body = "<html....";
or
var data = {
title: "page title",
body: "<html...."
};
it is very same thing.
If you want to learn more about JSON point your browser to http://json.org.
===== alternative =====
Alternative to json solution could be just plane ajax call to server and response can be plain HTML (from your question I can assume that you have something like this already). So instad of calling $.getJSON you can use $.get(url, callback); to do same thing. The code at the top of my answer will not dramatically change. Instead of geting JSON in response you will get string which is HTML.
----------- BOTTOM LINE -------
I prefer JSON since it can be easily extended later with other attributes, so there is no painful code changes later ;)
Problem here will be that when you return the full page and render it using the ajax response, your tinymce instance has not been shut down before.
In order to do this you can call this small piece of code before you render the ajax response:
tinymce.execCommand('mceRemoveControl',true,'editor_id');
In this case the editor should initialize correctly. You are not allowed to initialize a tinymce editor with the same id before shutting the first one down.
Strangely i ran into this problem yesterday. Following code should work, but YMMV. Trick is to use the correct steps in ajax events. I used the Regular TinyMCE and made use of the jQuery library already included.
Following goes into your tinyMCE initialization tinyMCE.init() . All of the below block should be outside the document.ready.
myTinyInit = {
//.......All essential keys/values ...........
setup : function(ed) {
ed.onChange.add(function( ed ) {
tinyMCE.triggerSave();
}) }
//.....................
};
// Init the tinyMCE
tinyMCE.init(myTinyInit);
This ensures the content is being saved regularly onto the textarea that holds the value. Next step is setting up the request events.
Normally tinyMCE mceAddControl before the ajax post and mceRemoveControl after the ajax success should do the trick. But I found that often does not work.
I used the form as the jQuery selector in my case.
jQuery( '.myForm' )
.find( 'textarea#myTextArea' )
.ajaxStart(function() {
// If you need to copy over the values, you can do it here.
// If you are using jQuery form plugin you can bind to form-pre-serialize event instead.
// jQuery( this ).val( tinyMCE.get( jQuery( this ).attr( 'id' )).getContent() );
}).ajaxSend( function() {
// ! - step 2
// My case was multiple editors.
myEds = tinyMCE.editors;
for( edd in myEds ) {
myEds[ eds ].remove();
}
// tinyMCE.get( 'myTextarea' ).remove();
// strangely mceRemoveControl didnt work for me.
// tinyMCE.execCommand( 'mceRemoveControl', false, jQuery( this ).attr('id'));
}).ajaxSuccess(function() {
// Now we got the form again, Let's put up tinyMCE again.
txtID = jQuery( this ).attr( 'id' );
// ! - step 3
tinyMCE.execCommand( 'mceAddControl', false, txtID );
// Restore the contents into TinyMCE.
tinyMCE.get( txtID ).setContent( jQuery( this ).val());
});
Problems i came across :
Using mceRemoveControl always gave me r is undefined error persistently.
If you get a blank tinyMCE editor, check the DOM whether the ID of the textarea is replaced with something like mce_02, this means that TinyMCE is being initialized again or something is wrong with the order. If so, the tinyMCE is duplicated with each save.
if you are new to JS, I recommend using jQuery with the form plugin, it might be easier for you. But do use the regular non-jquery tinyMCE, as it is well documented.
I fixed this problem by recalling the function after the ajax call. In this part of my ajax:
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("Content").innerHTML=xmlhttp.responseText;
tinymce();
Now it works fine.
How do i attach an onclick event to Placemarks specified in the KML file. Can event listeners be added to both google maps and google earth plugin?
How would I go about this?
In the Google Earth plugin...
google.earth.fetchKml(ge, href, function(kmlObject) {});
google.earth.addEventListener(kmlObject, 'click', function(event) {
event.preventDefault();
var kmlPlacemark = event.getTarget();
alert(kmlPlacemark.getName());
});
In Google Maps API
var ctaLayer = new google.maps.KmlLayer('http://www.****.com/index.kml');
ctaLayer.setMap(map);
google.maps.event.addListener(ctaLayer, 'click', function(kmlEvent) {
var text = kmlEvent.featureData.description;
alert(text);
});
Seemingly the onlick event is wrapped up when the kml loads (GMaps v3, kml with Placemarks) Any Placemark references to "BallonStyle" bundled in the same kml file causes these to replace the default popup - and you can achieve a lot with them.
These are the kml elements supported by Gmaps v3 http://code.google.com/apis/kml/documentation/kmlelementsinmaps.html
If your question is how to intercept that onlick event, then I am sorry I do not know how you can achieve that.
