JavaScript 封装Ajax传递的数据代码

复制代码 代码如下:
var paramBeanList = new Array();
Array.prototype.addParamBean=function(paramBeanObj){
    var index = this.containParamBean(paramBeanObj);
    if (index != -1) {
        this[index] = paramBeanObj;
    } else {
        this.push(paramBeanObj);
    }
};
Array.prototype.clear=function(){
    if (this.length == 0) {
        return;
    }
    for (var index in this) {
        this.pop();
    }
};
Array.prototype.containParamBean=function(paramBeanObj){
    var index = -1;
    if (this.length == 0) {
        return index;
    }
    for (var tempIndex = 0, step = this.length; tempIndex < step; tempIndex++) {
        if (this[tempIndex].compare(paramBeanObj) == 0) {
            index = tempIndex;
            break;
        }
    }
    return index;
};
var ParamBean = new function(pkCode, opDate, value) {
    this.pkCode = pkCode;
    this.opDate = opDate;
    this.value = value;
};
ParamBean.prototype={
toString:function() {
return "[pkCode:" + this.pkCode + ",opDate:" + this.opDate +",value:" + this.value + "]";
    },
    doVerify:function() {
        return (this.pkCode ? this.opDate ? this.value ? "true" : "false" : "false" : "false");
    },
    compare:function(otherObj) {
        var result = -1;
        if (otherObj) {
            if (this.pkCode == otherObj.pkCode && this.opDate == otherObj.opDate
                && this.value == otherObj.value) {
                result = 0;
            }
        }
        return result;
    }
};
var ParamUtils = new Object();
ParamUtils.doCreateAjaxStr=function() {
    var paramStr = "";
    if (paramBeanList.length == 0) {
        return paramStr;
    }
    var keyParamArray = new Array();
    var valueParamArray = new Array();
    for (var index = 0, step = paramBeanList.length; index < step; index++) {
        var tempObj = paramBeanList[index];
        keyParamArray.push(tempObj.pkCode + "`" + tempObj.opDate);
        valueParamArray.push(tempObj.value);
    }
    paramStr = "KEY_PARAM=".concat(encodeURIComponent(keyParamArray.join(","))).concat("&").concat("VALUE_PARAM=".concat(encodeURIComponent(valueParamArray.join(","))));
    return paramStr;
};

这篇文章我写了一会，到了csdn上弄了半天提不上去，我用IE6切到高级编辑，内容直接就是空，最后用Firefox浏览器竟然又提上来了。。
