Question

在ajax中两个数组，分别是arr1，arr2；怎样将数组分别传递到echarts中的nodes:[]和links:[]中？求详细源码!

部分源码

 <div id="main" style="height:500px;"></div>
<script src="./js/echarts.js" ></script>
<script src="./js/jquery-1.8.3.min.js" ></script>
<script>
var arr1 = [];
var arr2 = [];
$.ajax({
    type:"POST",
    async:false,
    url:"mapdata.php",
    dataType:"json",
    success: function(result){
        var str = result;
        for (var i = 0; i < str.length; i++) {
            arr1.push("{"+"category:"+str[i].category,"name:'"+str[i].name+"'","value:"+str[i].value+"}");
            }
        //document.write(arr1);
        for (var i = 0; i < str.length; i++) {
            arr2.push("{"+"source:'"+str[i].source+"'","target:'"+str[i].target+"'","weight:"+str[i].weight,"name:'"+str[i].name_nexus+"'"+"}");
            }
        //document.write(arr2);
        },
    error:function(errorMsg){
        alert("请求数据失败!");
        },
    });

require.config({
