var json = {};
var

在javascript中，对象本身就是一种Map结构。

var
map = {};
map[
'key1'
] = 1;
map[
'key2@'
] = 2;
console.log(map[
'key1'
]);
//结果是1.
console.log(map[
'key2@'
]);
//结果是2.
//如果遍历map
for

var
prop
in
map){
if

console.log(

动态拼接多个json对象为一个
var json="";
proSourceData.projectDesc=$("#proSourceDesc").val().trim();
proSourceData.projectName=$("#proSourceName").val().trim();
$("#usedTbody tr").each(function (index,item) {
var proObj={};
proObj[""+$(this).children().eq(0).text()+""]=$(this).children().eq(1).text();
json+=JSON.stringify(proObj);
json = json.replace(/}{/,',');
});
proSourceData.ruleList=eval("("+json+")");
var strProSourceData=JSON.stringify(proSourceData);
动态获取json中的value
var ruleList=proResource.ruleList;
var proStr="";
for(var prop in ruleList){
if(ruleList.hasOwnProperty(prop)){
proStr+=ruleList[prop]+",";
}
; }
