用户拖动时如何使用JQuery检测值更改事件将文本放入文本框? [英] How to use JQuery to detect value-changed event when user drag & drop text into textbox?

问题描述

我正在使用这个 jQuery 代码

I'm using this jQuery code

$('input').bind('change mouseup', ... )

检测用户是否将文本拖动到我的输入中改变它的价值.但这似乎行不通.为什么它不起作用以及如何让它起作用?

to detect if user drag text somewhere into my input & change it value. But that seems doesn't work. Why doesn't it work and how I can get it to work?

推荐答案

var inputField = $("input");
var oldValue = inputField.text();
inputField.bind("drop", function() {
    //when the drop happens the input value will not be updated yet
    //use a timeout to allow the input value to change.
    setTimeout($.proxy(function() {
        if (this.value !== oldValue) {
            $(this).trigger('change');
        }
    }, this), 0);
});
$("input").bind("change", function() {
    oldValue = this.value;
});
