var json = {};
var json1 = {a:1,b:1};var json2 = {c:1,d:1};json = eval('('+(JSON.stringify(json1)+JSON.stringify(json2)).replace(/}{/,',')+')');// json: {a:1,b:1,c:1,d:1}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mapfor(var prop in map){ if(map.hasOwnProperty(prop)){ console.log('key is ' + prop +' and value is' + map[prop]); }} |
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]+",";
}
; }
