i can't get this to work in smarty template (.tpl), although it works fine when using plain html. When user selects from dropdown, the image gets replaced. What is happening in template is the replaced image shows blank, which suggests it can't find the src.

<script>
function displayResult(selTag)
{
var x=selTag.options[selTag.selectedIndex].text;
alert("You selected: " + x);
document.getElementById('temp_image').src='images/'+ x +'.jpg';
}
</script>

<div class="configoptions">
{foreach from=$configurableoptions item=configoption}
{if $configoption.optiontype eq 1}
<select name="configoption[{$configoption.id}]" id="configoption[{$configoption.id}]" onchange="displayResult(this); recalctotals();">
{foreach key=num2 item=options from=$configoption.options}
<option value="{$options.id}"{if $configoption.selectedvalue eq $options.id} selected="selected"{/if}>{$options.name}</option>
{/foreach}
</select>
<br />
<img id="temp_image" src="images/templates/{$options.name}.jpg">
you've defined {$options} inside a foreach loop containing the elements from {$configoption.options} which itself contains items from {$configurableoptions}. Unfortunately this definition is out of scope since its outside the foreach-loop:
<img id="temp_image" src="images/templates/{$options.name}.jpg">
To (by default) display the first element of {$options} you could try something like this:
<img id="temp_image" src="images/templates/{$configurableoptions[0].options[0].name}.jpg">

Need to check format of the value of a textfield inside the Javascript.
I am using thymeleaf for rendering the page.
To achieve this I plan to use th:id and use this inside Javascript (similar to document.getElementById and read the value. But I donot know how to get the value of the textfield inside the javascript as I am doing an iteration..
Below is the scenario
While iterating through a Map<String,Field> (where Field is a class containing two elements fieldValueList (List) and timeField(boolean) check for the format of the textField entered in the page, (format of the textfield should be hh:mm:ss) need to be done in javascript. I used id for reading the value, but donot know how to get the value of the textfield inside the javascript.
The code for the page is
<fieldSet th:each="fieldKey,fieldKeyIndex : *{recipeFieldMap.keySet()}">
<div class="fieldDiv" th:each="fieldVal,field : *{recipeFieldMap[__${fieldKey}__].fieldValueList}">
<span class="fieldSpan" th:if="*{recipeFieldMap[__${fieldKey}__].timeField}">
<input type="text" th:id="|text_${fieldKeyIndex.index}_${field.index}|" th:field="*{recipeFieldMap[__${fieldKey}__].fieldTimeValueList[__${field.index}__].displayStr}" onchange="checkTimeStr()">
<script th:inline="javascript">
/*<![CDATA[*/
function checkTimeStr() {
// Something like this.. to read the value
//var value = document.getElementById('/* text_${groupKeyIndex.index}_${field.index} */').value;
//alert(value)
}
/*]]>*/
</script>
</span>
<span class="fieldSpan" th:unless="*{recipeFieldMap[__${fieldKey}__].timeField}">
<input type="text" th:field="*{recipeFieldMap[__${fieldKey}__].fieldValueList[__${field.index}__]}">
</span>
</div>
</fieldSet>
enter image description here
try this:
<script th:inline="javascript">
[[${field.index}]]
</script>
I want to change the CSS class of every second element within an included partial. Here is a code example of the output I want:
<p class="rec"></p>
<p class="sent"></p>
<p class="rec"></p>
<p class="sent"></p>
This is what I tried it so far:
<?php $derp = (isset($derp) && $derp == 'rec') ? 'sent' : 'rec'; ?>
<p class='<?php echo $derp; ?>'>
//CONTENT
</p>
I need help to get this working. I don't want to use the nth-child selector or JavaScript to change the class.
//update:
#forelse($statuses as $status)
#include('statuses.partials.status')
#empty
<div class="notif blue">
<span>This user hasn't yet posted a status.</span>
<span class="icon icon-info-sign"></span>
</div>
#endforelse
The partial get looped like this.
You can use pure CSS for this, using the nth-child selector and the even and odd parameter. In your CSS file simply add:
p:nth-child(odd) {
// This is the odd element so 1, 3, 5, .. element
}
p:nth-child(even) {
// This is the even element so 2, 4, 6, .. element
}
It's working now. I had to keep the code outside of the included partial and not in the partial itself. This made the difference! Anyways, still appreciate the given help!
I have read many times that you can NOW get getElementsByClassName. This below works fine IF I replace ClassName by Id, but using the word ClassName does not work. Anyone know why? (I tried on Chrome and Firefox)
<script type="text/javascript">
function makeDisable(){
var x=document.getElementsByClassName("mySelect");
x.disabled=true
}
function makeEnable(){
var x=document.getElementsByClassName("mySelect");
x.disabled=false
}
</script>
<form>
<select class="mySelect" id="mySelect">
<option>Apple</option>
<option>Banana</option>
<option>Orange</option>
</select>
<input type="button" onclick="makeDisable()" value="Disable list">
<input type="button" onclick="makeEnable()" value="Enable list">
</form>
The function is called getElementsByClassName. Plural. It returns not an element, but an array of all the elements that have the class name.
So even if the array consists of only one item, even there is only one element in the array, you still need to index it.
x[0].disabled=true
instead of
x.disabled=true
Fiddle
So to keep it simple, im trying to update my select list with a new list of items that i get from an ajax-call. The list has the items. I set the model to the new list and do a $scope.$apply(). This works great in firefox, but not in IE. What am I doing wrong? Is there some IE9-thing that I'm missing? (I've been looking for a few hours now and am ready to give up). Appreciate all the help I can get.
HTML:
<select
ng-model="SelectedParameter"
ng-options="Parameter.Name for Parameter in AllParameters">
</select>
JS:
$.getJSON("/Cont/GetList", {id: id},
function (result) {
var allParameters = result.Data.AllParameters;
$scope.AllParameters = allParameters;
$scope.$apply();
}
);
You'd be way better off doing this the "Angular way". No JQuery required! In fact, if you find yourself doing things the "JQuery way" you're probably doing it wrong. Mark Rajcok had a really good question (and answer) about this same thing on StackOverflow a while ago:
app.js
//declare your application module.
var app = angular.module('myApp', []);
//declare a controller
app.controller('MainCtrl', function($scope, $http) {
//function to update the list
$scope.updateList = function () {
$http.get('/Cont/GetList', function(data) {
$scope.allParameters = data;
});
};
//initial load
$scope.updateList();
});
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="angular.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="MainCtrl">
<button ng-click="updateList()">Update</button>
<ul>
<li ng-repeat="parameter in allParameters">{{parameter | json}}</li>
</ul>
<!-- EDIT: Because you requested a select.
or if you wanted to do a select list
assuming every object in your array had a "name" property
you wanted to display in the option text, you could do
something like the following:
(NOTE: ng-model is required for ng-options to work)
-->
<select ng-model="selectedValue" ng-options="p as p.name for p in allParameters"></select>
<!-- this is just to display the value you've selected -->
<p>Selected:</p>
<pre>{{selectedValue | json}}</pre>
</div>
</body>
</html>
EDIT: A common problem in IE
So first of all, if you're having a problem in IE, I'd recommend hitting F12 and seeing what errors you're getting in the console.
The most common issue I've seen that breaks things in IE relate to commands such as console.log() which don't exist in IE. If that's the case, you'll need to create a stub, like so:
//stub in console.log for IE.
console = console || {};
console.log = console.log || function () {};
I think it's an IE issue. Try setting display:none before you update, then remove the display setting after you update.
I believe it is this bug that is ultimately the problem. I've been pulling my hair out for a couple of days on something very similar, a select filtered off of another.
At the end of the day OPTIONS are being added dynamically and IE9 just chokes on it.
<div class="col-lg-2">
<div class="form-group">
<label>State</label>
<select data-ng-model="orderFilter.selectedState"
data-ng-options="s.StateAbbr for s in states"
data-placeholder="choose a state…"
class="form-control">
<option value=""></option>
</select>
</div>
</div>
<div class="col-lg-2">
<div class="form-group">
<label>County</label>
<select data-ng-model="orderFilter.selectedCounty"
data-ng-options="c.CountyName for c in filteredCounties | orderBy:'CountyName'"
data-ng-disabled="orderFilter.selectedState == null"
data-placeholder="Choose a county…"
class="form-control">
<option value=""></option>
</select>
</div>
</div>

i'm learning it, but i cant find what's wrong in this!
i want the div2 to get data from the form in div1, called formulario.
i would like to know which item is selected and which button was clicked.
main html file:
<script src="utils/Scripts/prototype.js" type="text/javascript"></script>
<script type="text/javascript">
function sendf(formul, divi, php)
{
var params = Form.serialize($(formul));
new Ajax.Updater(divi, php, {method: 'post', parameters: params, asynchronous:true});
}
</script>
</head>
<body>
<div id="div1">
contenido div1
<form id="formulario" method="POST">
<select size="3" id="lista" onchange="sendf('formulario', 'div2', 'prodiv1.php');">
<option>elemento 1</option>
<option>elemento 2</option>
<option>elemento 3</option>
</select>
<input type="button" id="b1" value="bot1" onclick="sendf('formulario', 'div2', 'prodiv1.php');" />
<input type="button" id="b2" value="bot2" onclick="sendf('formulario', 'div2', 'prodiv1.php');" />
</form>
<div id="div2" style="background: blue;">
contenido div2
</div>
</div>
</body>
</html>
the php file, prodiv1.php:
<?
echo 'exec: prodiv1.php<br>';
print_r($_POST);
echo serialize($_POST);
if (isset($_POST))
{
foreach ($_POST as $key=>$value)
{
echo $key.'=>'.$value."<br>";
}
}
echo "select: ".$_POST['lista'];
if (isset($_POST['b1'])) {echo 'click: boton1';} else {echo 'click: boton2';}
?>
i've tried a lot of things, and seen that it could be done with event observers, httprequests and such, but what i need is quite easy, and probably there's an elegant way to solve it...
i thank in advance any help!
have a nice day.

if you dont need to actually process the form contents in some way then you have no need to use Ajax to pass to a PHP script. Depending on what exactly you wanted to display in div 2 you could do something as simple as this:
function sendf()
{
var listvar = $('lista').value;
$('div2').update('select menu value was ' + listvar);
}
This is obviously missing quite a lot of detail and can be massively improved but it should highlight the fact that AJAX is not required.
Edit Looking at the rest of the code you have posted, is AJAX really required for this? surely you are just updating the existing page with data already present on the page, the server has no real part to play in this?
Sorry to dive into jQuery again, but this should allow you to get the values into "div2" without an ajax request.
$(document).ready(function() {
$("input").click(function(e) {
$("#div2").html($(this).attr("id")+" clicked<br />");
updateList();
});
});
function updateList() {
$("#div2").append($("#lista").val() + " selected");
}
In plain English this code says "if an input element is clicked, update the value of div2 with the input variables id, and append the selected value from the list to the result". Hopefully that makes sense to you :)
If you need an easy, elegant way to solve this with AJAX, use the jQuery library's ajax and post methods. For more information take a look here, it will significantly cut down on the size and complexity of your code.
