JavaScript 封裝Ajax傳遞的數(shù)據(jù)代碼

更新時(shí)間：2009年06月05日 22:34:19 作者：

在使用Ajax傳輸數(shù)據(jù)時(shí)，少不了對傳遞的字符進(jìn)行轉(zhuǎn)碼，我的實(shí)現(xiàn)方式是將需要傳遞的數(shù)據(jù)暫存到一js Bean中，將js Bean放到Array中，生成傳輸參數(shù)時(shí)對Array中的jsBean進(jìn)行分解，得到相應(yīng)屬性信息并編碼..

復(fù)制代碼代碼如下:

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; 
};
