把二维数组转换为json字符串

var data = [ ['选项1', 10], ['选项2', 10], ['选项3', 50],['选项4', 30] ];
var oneArr=[].concat.apply([],data);//["选项1", 35, "选项2", 15, "选项3", 25, "选项4", 25]
var jsonArr=[];
var nameArr=[];

for(var i=0;i<oneArr.length;i++){
    if(i%2==0){
        var dataName=oneArr[i];
        var str='{name:"'+oneArr[i]+'",value:'+oneArr[i+1]+'}';

	var jsonStr=eval('('+str+')');

	nameArr.push(dataName);

jsonArr. push( jsonStr);

    }

}

console.log(jsonArr);//[{name: "选项1", value: 10},{name: "选项2", value: 10},{name: "选项3", value: 50},{name: "选项4", value: 30}]

console.log(nameArr);//["选项1", "选项2", "选项3", "选项4"]
