}

<script src=config.js></script>
<script>
loadJS("edit");
</script>
//根据传入的key，动态生成js加载语句
function loadJS(sKey) {
        var node = JSHash[sKey];
        for(var i =0;i < node.length; i ++) {
                document.writeln(‘<script src="‘+node[i].url+‘?version=‘+node[i].version+‘"><\/script>‘);
