Image Cropping in Richfaces
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],
开发者_高级运维 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>

<body class="yui-skin-sam">

<div id="results"><img src="/app/css/images/apple.jpg"></div>
<ul>
<li>Height: (<span id="h">91</span>)</li>
<li>Width: (<span id="w">150</span>)</li>
<li>Top: (<span id="t">20</span>)</li>
<li>Left: (<span id="l">20</span>)</li>
</ul>
<input type="button" onclick="getValue()" value="click"/>
</tr>
</table>
</h:form>
</rich:modalPanel>
any ideas?
Richfaces does not conflict with jQuery. You can use jQuery.noConflict()
加载中,请稍侯......
