不要為 拼寫 ajax url 而郁悶了。希望能對大家有幫助。
/*?
??? 1.form?ajax?使用：
????eG: form就是普通的 html form
????????<input?type="button"?value="xx"?onclick="formAjax('data.jsp',this.form,ajaxReturn)"/>
????????function?ajaxReturn(data){
????????????document.getElementById("div1").innerHTML?=??data?;
????????}
??
????
??? 2.ajax?使用???：
????AjaxFunction
????????AjaxFunction('url?param=tt¶m2=te',function(text){??
????????????alert(text);
????????});
??? 3.迭代器：
??? recursiveNodes(array,dom,pushFun,layer)
? ? ?? array 迭代寄存器
? ? ?? dom 被迭代對象
?????? pushFun 自定義收集方法
??????????? pushFun(array,node,layer)
?????????????? node 迭代中對象
?????? layer 深度
??? EG:
??? var arr = [] ;
??? recursiveNodes(arr ,dom,function(array,node,layer){
??????????? arr.push(node);
???? },2);
