html常用组件Js控制代码模板

1. Ajax请求

var IpAndPort = 'http://' + window.location.hostname +
 ':' + window.location.port;
$.ajax({
        url: IpAndPort + "/sys/xxx",
        type: "POST",
        data: {sysId: sysId},
        dataType: "json",
        success: function (result) {
        },
        error: function (request, errorType, errorMsg) {
            alert("删除失败");
        }
    })

2. 获取下拉框的多个选中数值

        var array = [];
        $('#system_list option:selected').map(function () {
            array.push($(this).val());
        });
        for (var i = 0;i < array.length;i ++){
            console.log(array[i]);
        }
