JQuery异步提交表单、HTML提交表单到新窗口或IFrame

一个工具类，据说JQuery框架，实现异步表单提交，同时添加将表单数据提交到新窗口和IFrame的方法

// 定义函数命名空间Kevin = new Object();/** * 异步提交表单 */Kevin.submitAjaxForm=function(formId, url, succback, isunlock){ jQuery.ajax({        url: url,   // 提交的页面        data: $("#" + formId).serialize(), // 从表单中获取数据        type: "POST", // 设置请求类型为"POST"，默认为"GET"        dataType: "json",        contentType: "application/x-www-form-urlencoded;charset=UTF-8", // 必须要设置为UTF-8，否则提交数据乱码        beforeSend: function(){        if(!isunlock){        new screenClass().lock();        }        },        error: function(msg) {      // 设置表单提交出错            new screenClass().unlock();alert("执行出错：" + msg.responseText);        },        success: function(resp) {         if(!isunlock){         new screenClass().unlock(); // 设置表单提交完成使用方法         }        if(resp.success == false){       alert("执行失败：" + resp.resultMsg);        }else if(resp.success == true){        if(succback == '' || typeof(succback) == "undefined"){       window.location.href="success.jsp";        }else{        succback(resp.attributes);        }        }else{        alert("未知结果：" + resp);        }        },        cache: false    });}/** * 将表单提交到新的窗口 */Kevin.submitToWindow=function(form, title, url, width, height){var title = title ? title : Math.floor(Math.random() * ( 1000 + 1));var winObj = window.open("", title, "toolbar=no, menubar=no, scrollbars=yes , resizable=no,location=no, status=no");var ie = navigator.userAgent.toLowerCase();ie = ie.match(/msie ([\d.]+)/)if(!ie){alert('请使用IE内核浏览器');}else{winObj.resizeTo(width , height);}var bakTarget = form.target;var bakAction = form.action;form.action = url;form.target= title;form.submit();form.target= bakTarget;form.action = bakAction;return winObj;}/** * 将表单提交到框架 */Kevin.submitToIFrame=function(form, target, url){if(target){var bakTarget = form.target;var bakAction = form.action;form.action = url;form.target= target;form.submit();form.target= bakTarget;form.action = bakAction;}else{alert('iframe的id不能为空');}}/** * 屏幕处理类 */var screenClass = function(){    /// 解锁    this.unlock = function(){        var divLock = document.getElementById("divLock");        if(divLock == null) return;        document.body.removeChild(divLock);    };        /// 锁屏    this.lock = function(slow){        var sWidth,sHeight;        var imgPath = slow ? "img/waiting_slow.gif" : "img/waiting_fast.gif";        sWidth  = document.body.clientWidth;        sHeight = document.body.clientHeight;                var bgObj=document.createElement("div");        bgObj.setAttribute("id","divLock");        bgObj.style.position="absolute";        bgObj.style.top="0";        bgObj.style.background="#cccccc";        bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75";        bgObj.style.opacity="0.6";        bgObj.style.left="0";        bgObj.style.width=sWidth + "px";        bgObj.style.height=sHeight + "px";        bgObj.style.zIndex = "100";        document.body.appendChild(bgObj);        var html = "<table border=\"0\" width=\""+sWidth+"\" height=\""+sHeight+"\"><tr><td valign=\"middle\" align=\"center\"><image src=\""+imgPath+"\"></td></tr></table>";        bgObj.innerHTML = html;        // 解锁        bgObj.onclick = function(){             //new screenClass().unlock(); // 应该等完成后再解锁        };    };}
