Richfaces 中的图像裁剪
JQuery 和 Java Script 中有多种可用的图像裁剪工具。我尝试将这些工具与 Richfaces 应用程序集成。由于 jquery 冲突出现，我转移到 YUI，它工作得很好。但我无法捕获托管 bean 的坐标值。 我需要捕获坐标并且应该将其保留。这是代码示例。
<style type="text/css" media="screen">
#results {
border: 1px solid black;
height: 83px;
width: 125px;
position: relative;
overflow: hidden;
}
#results img {
position: absolute;
top: -20px;
left: -20px;
}
</style>
<script>
(function() {
var Dom = YAHOO.util.Dom,
Event = YAHOO.util.Event,
results = null;
Event.onDOMReady(function() {
results = Dom.get('results');
var crop = new YAHOO.widget.ImageCropper('yui_img', {
initialXY: [20, 20],
keyTick: 5,
shiftKeyTick: 50
});
crop.on('moveEvent', function() {
var region = crop.getCropCoords();
results.firstChild.style.top = '-' + region.top + 'px';
results.firstChild.style.left = '-' + region.left + 'px';
results.style.height = region.height + 'px';
results.style.width = region.width + 'px';
Dom.get('t').innerHTML = region.top;
Dom.get('l').innerHTML = region.left;
Dom.get('h').innerHTML = region.height;
Dom.get('w').innerHTML = region.width;
});
});
})();
function getValue()
{
alert("Inside");
//alert(document.getElementById('h').innerHTML)
}
</script>
<rich:modalPanel id="addProductLinksModalPanel" autosized="true"
domElementAttachment="parent"
onshow="javascript:scroll(0, 0);"
rendered="true" width="850" height="300" minWidth="850" minHeight="300" >

有什么想法吗？
There are various Image cropping tools available in JQuery and Java Script. I try to integrate any of these tools with Richfaces application. Since jquery conflict arises i moved to YUI which works fine. But I cant catch the coordinates value to the managed bean.
I need to capture the coordinates and it should be persisted. Here is the code sample.
<style type="text/css" media="screen">
#results {
border: 1px solid black;
height: 83px;
width: 125px;
position: relative;
overflow: hidden;
}
#results img {
position: absolute;
top: -20px;
left: -20px;
}
</style>
<script>
(function() {
var Dom = YAHOO.util.Dom,
Event = YAHOO.util.Event,
results = null;
Event.onDOMReady(function() {
results = Dom.get('results');
var crop = new YAHOO.widget.ImageCropper('yui_img', {
initialXY: [20, 20],
keyTick: 5,
shiftKeyTick: 50
});
crop.on('moveEvent', function() {
var region = crop.getCropCoords();
results.firstChild.style.top = '-' + region.top + 'px';
results.firstChild.style.left = '-' + region.left + 'px';
results.style.height = region.height + 'px';
results.style.width = region.width + 'px';
Dom.get('t').innerHTML = region.top;
Dom.get('l').innerHTML = region.left;
Dom.get('h').innerHTML = region.height;
Dom.get('w').innerHTML = region.width;
});
});
})();
function getValue()
{
alert("Inside");
//alert(document.getElementById('h').innerHTML)
}
</script>
<rich:modalPanel id="addProductLinksModalPanel" autosized="true"

Richfaces 与 jQuery 并不冲突。您可以使用
jQuery.noConflict()Richfaces does not conflict with jQuery. You can use
jQuery.noConflict()
