In a Controller, I have a handler method that should pass a string to a jsp named searchResultGraph.jsp
#RequestMapping(value = PATHELEM + "/searchGraph")
public String handleGraph(Model model) {
String write = writer.getWriteString();
model.addAttribute("write", write);
System.out.println(write);
return PATHELEM + "/searchResultGraph";
}
the jsp looks like this:
<?xml version="1.0" encoding="ISO-8859-1" ?>

But nothing is displayed when I try to call ${write}. Is there something missing in my method?
Thanks!
CHECK ARE YOU HAVING A METHOD NAMED getWriteString(); in you bean class and if not create a class name Write and instantiate an object named write in your controller and then pass some string into that and add that to the model to return that by you controller,
Write write = new Write();
write.getWriteString();
Ok, I found the solution:
The links in options-tag had to be relative links too!
So instead of this
var options = {
swfPath: "CytoscapeWeb",
flashInstallerPath: "playerProductInstall"
};
I had to write this:
var options = {
swfPath: "<c:url value="/resources/js/CytoscapeWeb" />",
flashInstallerPath: "<c:url value="resources/js/playerProductInstall" />"
};

I seem to have a very specific problem where something is missing and I just can't see it.
From and index.html:
<!DOCTYPE HTML>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>
<body onLoad="javascript:Scan()">
<div id = "TheDiv">?
</div>
</body>
</html>
From onLoad, I call Scan()
function Scan()
{
divResultado = document.getElementById('TheDiv');
//instanciamos el objetoAjax
ajaxScan=objetoAjax();
ajaxScan.open("GET", "myscan.php", true);
DBScan = setTimeout(Scan,15000 );
ajaxScan.onreadystatechange=function()
{
if (ajaxScan.readyState==4)
{
//mostrar resultados en esta capa
divResultado = ajaxScan.responseText;
}
};
ajaxScan.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
ajaxScan.send( );
}
myscan gets data from a database and in debug, I see that information is properly transfered to divResultado above.
But the data doesn't appear in the div with id = "TheDiv"
I've done this hundreds of times before, but something somwhere has made itself
invisible to me.
In the raw data HTML, I think it appears below and outside of the context.
What am I not seeing
Because you're not writing the data to the page, you're just assigning it to a variable:
divResultado = ajaxScan.responseText;
Which means divResultado no longer refers to the element on the page, it now refers to the text from the AJAX response.
To set the text to that element, try:
divResultado.innerText = ajaxScan.responseText;
Or, if the result is HTML:
divResultado.innerHTML = ajaxScan.responseText;
I have a simple page which uses the mediaelement.js audioplayer plugin. The player attaches and functions correctly when loaded normally. However, when the page is loaded via ajax, the mediaelementplayer does not attach to the audio tag.
I use this code to call the file via ajax and jquery:
<html>
<head>
<link href="/test-vocabulary.css" rel="stylesheet" type="text/css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(".ajax_vocab_link").click(function(evento){
evento.preventDefault();
var ajaxDivNum = $(this).attr('id').split('_')[1];
var searchTerm = $(this).attr('title');
$("#ajaxcontainer_"+ajaxDivNum).load("test-audioplayer-se.php", {chrisSearch: searchTerm}
);
});
})
</script>
</head>
<body>
<p><button class='ajax_vocab_link' id='ajaxlink_1' title='clothes'>Link to load ajax doc</button></p>
<div class='ajax_vocab_container' id='ajaxcontainer_1'>This is div id ajaxcontainer_1</div>
</body>
</html>
The audioplayer page is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<link rel="stylesheet" href="http://www.ingles23.com/audioplayer/css/style4.css" media="screen">
<!-- end Audio Player CSS & Scripts -->
<script>
$(document).ready(function() {
$('#audio-player-vocab0').mediaelementplayer({
alwaysShowControls: true,
features: ['playpause'],
audioVolume: 'horizontal',
audioWidth: 400,
audioHeight: 120
});
});
</script>
</head>
<body>
<div class='display_vocab_container' >
<div class='display_vocab_text' >
<div class='audio-player-slim'>
<audio controls='controls' type='audio/mp3' src='/sound/mp3/i23-crear-frases-ingles-5.mp3' id='audio-player-vocab0'></audio>
</div>
</div>
</div>
</body>
</html>
I've tried many combinations including using on, live, success and moving the css/js links between the documents, but these have all made the situation worse.
What can i do get the file to attach medaielementplayer when loaded via ajax?
Try to put the mediaelementplayer() function call in the ajax success function, that worked for me. So unless you want to use .ajax instead of .load you'll need to pass it as the second argument to the load function. Or use http://api.jquery.com/ajaxSuccess/
$(".ajax_vocab_link").click(function(evento) {
evento.preventDefault();
var ajaxDivNum = $(this).attr('id').split('_')[1];
var searchTerm = $(this).attr('title');
$("#ajaxcontainer_"+ajaxDivNum).load("test-audioplayer-se.php", function() {
$('#audio-player-vocab0').mediaelementplayer({
alwaysShowControls: true,
features: ['playpause'],
audioVolume: 'horizontal',
audioWidth: 400,
audioHeight: 120
});
});
});
This code below works fine in Chrome and IE 9. But breaks in IE 8.
The errant line is here. I think it's the bind.
google.maps.event.addListener(this.map, "click", (this.leftClick).bind(this));
Has anyone else had this problem? It's not clear if someone has this on SO.

i have script like this....

<meta name="author" content="bbbbb" />
<script type="text/javascript" src="js/jquery-1.5.1.js"></script>

div{

$(document).ready(function()

$('div').click(function(){
$(document).load('load.html');
} );
});

</head>
<body>
<div id="init">Click Me</div>
<div id="div1">Div 1</div>
<div id="div2">Div 2</div>
</body>
</html>
in load.html i have a paragraph with with dummy content.
why this script is not changing my content of page...
loading a document object inside other is allowed or not?
You should change $(document).load('load.html'); to $('body').load('load.html');:
$(document).ready(function()
{
$('div').click(function(){
$('body').load('load.html');
return false;
});
});
When I execute the code below in IE7/WinXP32, then the output in the console is "undefined". The output changes to the expected "getContext()", when I make either of two modifications:
I remove the image tag.
I use: <body onload="draw()">
Any idea what is going on here? What may be a workaround?

Update: Seems like replacing "dojo.addOnLoad(draw);" with the following code does the trick.
function init() {
dojo.addOnLoad(draw);
}
if (dojo.isIE) {
dojo.connect('onload', init);
} else {
init();
}
dojo.addOnLoad fires before document.onload. I think it's associated with DOMContentLoaded. Perhaps excanvas does its initialization on the same event? Can you just use document.onload?
