交换两个文本框值 [英] Swapping two text box values

问题描述

我有两个文本框值:-

var pickup = $('#txt-pickup');
var destination = $('#txt-destination');

，我想交换两个值，如下所示:-

and I want to swap the two values as follows:-

pickup.val(destination.val());
destination.val(pickup.val());

但是，以上将始终将两个值设置为相同的值. (与目标值相同)

However, the above will always set both values as the same value. (same as the destination value)

有没有办法同时更改这两者?

Is there a way of changing both of these at the same time?

推荐答案

我为您制作了一个jsfiddle:

I made a jsfiddle for you:

<input id="txt-pickup" type="text"/>
<input id="txt-destination" type="text"/>
<input id="change" type="button" value="Swap"/>

$(document).ready(function (){

    $("#change").on('click',function(){
        var pickup = $('#txt-pickup').val();
        $('#txt-pickup').val($('#txt-destination').val());
        $('#txt-destination').val(pickup);


    });

});
