That's because when you load your content with AJAX, scripts are not interpreted. You have to evaluate them by yourself using the eval() function. Or, since you're using Dojo, you could look at the dojox/layout/ContentPane module. This module allows you to load a page (through AJAX requests) and execute the scripts that are on it without the entire XMLHttpRequest or ActiveXObject overhead (and without having to manually call eval()).
To do this with the dojox/layout/ContentPane, you just replace your <div> with ID #txtHint by:
<div data-dojo-type="dojox/layout/ContentPane" id="txtHint" data-dojo-props="href: 'welcome.jsp', executeScripts: true">
Customer info will be listed here...
</div>
You only need to make sure you load Dojo, set the data-dojo-config attribute so that parseOnLoad: true property is set and you need to make sure you import the dojox/layout/ContentPane module by having the following code:
require(["dojox/layout/ContentPane", "dojo/parser"]);
A full example loading a webpage can be found on this JSFiddle (I change the href to / so it would load the homepage again, because I have no welcome.jsp page).
Another example doing the same programmatically can be found on this JSFiddle.

I'm attempting to make a selection and pass the variable to a .php page. I can do it with the jQuery examples on a date selector ... but can't figure it out on the menu selector. When I use this control in conjunction with the datepicker, it allows me to pass both variables, but when I just use it by itself, it doesn't hand it off.

Use my code it will work. But make sure your jquery files jquery/js/jquery-1.10.2.js available in the right path or not?

roster.php file
<?php
echo $_POST['q'];

since you using jquery you can do it like bellow :
<script>
function showUser(str)
{
var datastring ;
datastring = "q="+str;
$.post("roster.php",datastring,function(){
//your result here
});
}

Dude i can see in your code that you are using jQuery on the page.
can use jQuery provided methods for Ajax requests.
$.get
$.post
And more verbose method $.ajax for your work you need jQuery to make it cross browser.
$.get('/test2.php?date='+date,function(response){
//use server response to manipulate dom
});
I've been attempting to put together a website that requires obtaining xml data from another website. So far, using only html and javascript (no twitter bootstrap), I can access the website XML and populate a select dropdown menu. Here is the non-bootstrap html code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="js/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="js/getXML.js"></script>
</head>
<body>
<h1>Test App</h1>
<button id="button1">submit</button>
<select id="selectState"></select>
</body>
</html>
and here is the bootstrap html code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<select id="selectState"></select>
<button type="submit" class="btn btn-default" id="button1" >submit</button>
</form>
</div>
</div>
</div>
</html>
and here is the getXML.js script:
var HttpClient = function() {
this.get = function(aUrl, aCallback) {
anHttpRequest = new XMLHttpRequest();
anHttpRequest.onreadystatechange = function() {
if (anHttpRequest.readyState == 4 && anHttpRequest.status == 200)
aCallback(anHttpRequest.responseText);
}
anHttpRequest.open( "GET", aUrl, true );
anHttpRequest.send( null );
}
}
$(document).ready(function(){
$( "#button1" ).click(function () {
aClient = new HttpClient();
aClient.get('http://www.waterqualitydata.us/Station/search?characteristicName=Caffeine&mimeType=xml&bBox=-92.8,44.2,-88.9,46', function(data) {
xmlDoc = $.parseXML( data ),
$xml = $( xmlDoc ),
$LocName = $xml.find( "MonitoringLocationName" );
var arr = [];
$.each($LocName,function() {
arr.push( $(this).text() );
});
for ( var i = 0; i < arr.length; i = i + 1 ) {
$('#selectState').append('<option>'+arr[i]+'</option>');
}
alert( "success" );
});
});
});
Now, when I try and using the Twitter bootstrap html, I am getting a Cross-Origin Request Block due to the Same Origin Policy.
Is there any reason why the scripts that don't use Twitter Bootstrap can get around the SOP, while the twitter bootstrap version can't?
Modify the Bootstrap script to include the 'type' attribute, like so:
<script src="js/bootstrap.min.js" type="text/javascript"></script>
The 'type' parameter here is key - it is what allows the remote request to happen. CSS and JS are allowed to do this kind of cross domain linking, as it is judged by the W3C gods to be a low security risk (at least last I checked).
Check these links out for more information on CORS:
IE's explanation: http://msdn.microsoft.com/en-us/library/ie/gg622939%28v=vs.85%29.aspx
Mozilla's thoughts: https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy
OK, I think I found the problem. I was placing the <button> inside a <form> element. This apparently raises the SOP block. Without the <form> element, no SOP block was raised.
I haven't looked at the exact reason behind this, but maybe its related to a security feature baked into the <form> element, since <form> elements can be used to pass sensitive information (passwords, etc.)?
Below is the code I have been working on,
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/bootstrap-tagsinput.css" rel="stylesheet">
<script src="js/jquery.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/bootstrap-tagsinput.min.js"></script>
<script>
var request;
function sendInfo(){
var v=document.main.io.value;
var url="myjsp.jsp?val="+v;
if(window.XMLHttpRequest){
request=new XMLHttpRequest();
}
else if(window.ActiveXObject){
request=new ActiveXObject("Microsoft.XMLHTTP");
}
try{
request.onreadystatechange=getInfo;
request.open("GET",url,true);
request.send();
}catch(e){
alert("Unable to connect to server");
}
}
function getInfo(){
if(request.readyState==4){
var m=request.responseText;
document.getElementById('sam').innerHTML=m;
}
}
</script>
</head>
<body>
<form name="main">
<input type="text" name="io" onkeyup="sendInfo()" data-role="tagsinput"/>
</form>
<div id="sam">
</div>
</body>
I have not included the "myjsp.jsp" file as I'm sure that nothing is wrong with it.
If I create the textbox as follows,
<input type="text" name="io" onkeyup="sendInfo()"/>
then the function "sendInfo()" is called but if I add "data-role='tagsinput'" as,
<input type="text" name="io" onkeyup="sendInfo()" data-role="tagsinput"/>
then the function "sendInfo()" is not called.
I have to write data-role="tagsinput" for generating the bootstrap tags, but I also want the function "sendInfo()" to execute.
Any suggestions on this situation??
Thanks in advance.
you can add the event listener with javascript:
window.attachEvent = function(){
document.querySelector("input[data-role='tagsinput']").onkeyup(function(){
sendInfo();
});
};
window.addEventListener("load", attachEvent);
to make sure for accessibility of your function, define it in window context:
window.sendInfo=function sendInfo(){/.../}
and you can also try body onload attribute:
<body onload="attachEvent();">...</body>
I want to implement a suggestion combobox which shows suggestions grabbed from my own web service (using restapi and jsonp). I found that ComboBox.store.root.children contains suggestion's data and wrote the code below. For the simplicity I use there array instead of getting suggestions from my service.
The problem with that is it looks like a hack and some features don't work properly. For instance, I can't get rid of 'Search' phrase in the list.
Can you suggest more elegant solution?
