Symbian WRT中使用JS自动将XML、JSON转换成为对象

核心提示：for (var j = 0; j < optionsLength; j++) {var option = selfProcessData.options[j];//要从XML读取的节点名称var nodeName = option['nodeName'];//取得节点元素var da = ite

for (var j = 0; j < optionsLength; j++) {

var option = selfProcessData.options[j];

//要从XML读取的节点名称

var nodeName = option['nodeName'];

//取得节点元素

var da = items[i].getElementsByTagName(nodeName)[0];

//通过options取得对应的成员变量名称

var memberName = option['memberName'];

var nodeValueOrAttribute = option['nodeValueOrAttribute'];

var attributeName = option['attributeName'];

if (da != null || da != undefined) {

//判断是取节点的值还是其中的属性值

if (nodeValueOrAttribute == 'attribute' &&

(attributeName != undefined || attributeName != null)) {

selfProcessData.data1.putProperty(memberName, da.getAttribute(attributeName));

}

else {

if (da.firstChild == null || da.firstChild == undefined) {

selfProcessData.data1.putProperty(memberName, null);

}

else {

selfProcessData.data1.putProperty(memberName, da.firstChild.nodeValue);

}

}

}

else {

selfProcessData.data1.putProperty(memberName, null);

}

}

array[i] = selfProcessData.data1;

}

selfProcessData.processDataFunction(array);

}

json2.js - 用于处理JSON数据

Js代码

/**

* 将JSON转换成为string对象

*/

jsonToString = function(obj){

var THIS = this;

switch(typeof(obj)){

case 'string':

return '"' + obj.replace(/(["\])/g, '\$1') + '"';

case 'array':

return '[' + obj.map(THIS.jsonToString).join(',') + ']';

case 'object':

if(obj instanceof Array){

var strArr = [];

var len = obj.length;

for(var i=0; i<>
