IE11 + jQuery 1.8.3:动态添加带有占位符的textarea并将文本设置为占位符 [英] IE11 + jQuery 1.8.3: dynamically added textarea with placeholder has text set to placeholder

问题描述

这很可能是一个错误，但是我在这里报告该错误以供参考，也可能是某人有可能提出解决方法的机会.

This is very likely a bug, but I'm reporting it here for reference and for the slight chance of someone being able to propose a workaround.

IE 11本身在textarea元素上支持placeholder属性.那太棒了.但是，向DOM添加带有占位符的新textarea时，它也会自动将占位符文本放入textarea的字段中！

IE 11 supports the placeholder attribute natively on textarea elements. That's great. But adding a new textarea with a placeholder to the DOM, it automatically puts the placeholder text into the textarea's field, too!

推荐答案

摆在jsfiddle上，事实证明，从jQuery 1.9起，不会发生此问题:

Fiddling around on jsfiddle, it turns out that from jQuery 1.9 onwards, this problem does not occur: http://jsfiddle.net/wE577/2/.

确实是一个奇怪的问题.不幸的是，我的谷歌foo没有对此提出任何错误报告.

A weird problem indeed. Unfortunately, my google foo didn't turn up any bug reports on this.

此刻，我们无法将jQuery升级到1.8.3以上(尽管我希望不久以后)，我想到的解决方法是设置placeholder属性之后，并添加新的元素，可以完美地工作.

Since at the moment, we cannot upgrade jQuery beyond 1.8.3 (although I hope we soon will), a workaround I came up with is setting the placeholder attribute after adding the new textarea element to the DOM, which works flawlessly.
