J Queryynes 2 检查箱
原标题:JQuery Sync 2 Checkboxes

我将以下代码用于第二组投入箱。

$("#input_box_1").bind("keyup paste", function() {
    $("#input_box_2").val($(this).val());
});

上述工作十分出色,但我需要做同样的检查。

My question is...how do I modify the code for it to work with a checkbox?

最佳回答

在第一次检查箱变更时,需要根据第一个检查箱中该财产的价值修改<代码>浸入的财产(因此,我们必须遵守<代码>change>:

$("#checkbox1").change(function() {
    $("#checkbox2").prop("checked", this.checked);
});

请注意,你无需通过<代码>,即<>t/code>,以 into,你只能取用较快的原始OM元件的财产。

问题回答

Try something like:

$("#input_box_1").on("change", function() {
    $("#input_box_2").prop( checked , $(this).prop( checked ));
});

使用<代码>attr(支票)而不是val()

$("#input_box_1").bind("keyup paste", function() {
    $("#input_box_2").attr( checked , $(this).attr( checked ));
});
