原标题:jQuery on variable change, update textbox

在j Query,可以核对var x = []的改动,然后在文本箱中添加阵列的内容。

因此,如果X包含<代码>[1””2”,“3”]。 页: 1 页: 1

最佳回答

你们可以做这样的事情,避免使用监视器:

var Data = (function () {
    var _x = [],
        $textbox = $("#myTextbox");
    return {
        getX: function () {
            return x;
        },
        setX: function (x) {
            _x = x;
            // Setting  x  triggers an update
            $textbox.val(x.join(","));
        }
    }
}();

然后使用<代码>x,,并通过<代码>Data.getX(查询。

问题回答
var myString = myArray.join( , );
$( #textbox1 ).val(myString);

Don t 了解如何看到变化的变数,除非你制造一个有“不变”事件的物体,但要在文本框中显示这种数值。

$("#textboxID").val(x.join(","));

最容易的事情是具备上述法典的最新功能,并且只是呼吁在任何地方改变X的价值。

if ($.inArray(x, [1, 2, 3]) != -1) {
    $( #textbox1 ).val(x);
}
