    function getData() {

</script>

效果图：

var arrayObj = new Array();//创建一个数组
var arrayData = [];

arrayObj.push("1");
arrayObj.push("2");
arrayObj.push("3");
arrayObj.push("4");
arrayObj.push("5");

//Array追加数组对象
var moreData = [{ "vale": 100, "name": "电子商务" },{ "vale": 200, "name": "互联网" }];
Array.prototype.push.apply(arrayData, moreData);
arrayData = arrayData.concat(moreData);

arrayData.push({ "vale": $("#hidCount").val(), "text":"123" });
arrayData.push({ "vale": $("#hidCount").val(), "text":"123" });
arrayData.push({ "vale": $("#hidCount").val(), "text":"123" });
arrayData.push({ "vale": $("#hidCount").val(), "text":"123" });
arrayData.push({ "vale": $("#hidCount").val(), "text":"123" });

arrayData.push({ "objKey": $("#hidCount").val(), "objText": result.Data });
arrayData.push({ "objKey": $("#hidCount").val(), "objText": result.Data });
arrayData.push({ "objKey": $("#hidCount").val(), "objText": result.Data });
arrayData.push({ "objKey": $("#hidCount").val(), "objText": result.Data });
arrayData.push({ "objKey": $("#hidCount").val(), "objText": result.Data });


//数组长度
alert(arrayObj.length);

//数组转字符串
alert(arrayObj.join(","))

//json转字符串
alert(JSON.stringify(arrayData));


///删除arrayData元素
function DeleteLawyer() {
    $("#liLawyer" + $("#hidEditId").val()).remove();
    $.each(arrayData, function (index, item) {
        if ($("#hidEditId").val() == item.objKey.toString()) {
            arrayData.splice(index, 1);
            return;
        }
    });
    //alert(JSON.stringify(arrayData));
