Asp.Net形式DefaultButton错误在Firefox [英] Asp.Net Form DefaultButton Error in Firefox

问题描述

在.NET中产生code为用DefaultButton属性设置窗体中包含的JavaScript不佳，使功能在IE工作，但不能在其他浏览器（Firefox specifcially）。

The .Net generated code for a form with the "DefaultButton" attribute set contains poor javascript that allows the functionality to work in IE but not in other browsers (Firefox specifcially).

命中enter键确实与所有浏览器提交表单，但是当它发生在一个与LT的的Firefox不能忽视的关键preSS; textarea的＆GT;控制。结果是一个多行文本区域控制不能为多在Firefox的回车键提交表单，而不是创建一个新的行。

Hitting enter key does submit the form with all browsers but Firefox cannot disregard the key press when it happens inside of a <textarea> control. The result is a multiline text area control that cannot be multiline in Firefox as the enter key submits the form instead of creating a new line.

这可能是固定在Asp.Net 3.0 +但有解决方法仍然有2.0创建。

This could be fixed in Asp.Net 3.0+ but a workaround still has to be created for 2.0.

最轻的解决方法（一黑客工具，看起来并不像一个黑客= D）任何想法？在上面的链接的解决方案，让我害怕一点点，因为它可以很容易产生意想不到的副作用。

推荐答案

我用这个功能改编自codeSTA。

I use this function adapted from codesta.

您通过像这样一个div周围的code使用它。你可以继承的形式自动包括这一点。我不使用它那么多，所以我没有。

You use it by surrounding your code with a div like so. You could subclass the Form to include this automatically. I don't use it that much, so I didn't.

<div onkeypress="return FireDefaultButton(event, '<%= aspButtonID.ClientID %>')">
    (your form goes here)
</div>

下面的功能。

function FireDefaultButton(event, target) 
{
    // srcElement is for IE
    var element = event.target || event.srcElement;

    if (13 == event.keyCode && !(element && "textarea" == element.tagName.toLowerCase())) 
    {
    	var defaultButton;
    	defaultButton = document.getElementById(target);

    	if (defaultButton && "undefined" != typeof defaultButton.click) 
    	{
    		defaultButton.click();
    		event.cancelBubble = true;
    		if (event.stopPropagation) 
    			event.stopPropagation();
    		return false;
    	}
    }
    return true;
}
