输入按钮不提交表单(仅限 IE)ASP.NET

问题描述

我有一个带有文本框和按钮的表单.IE 是唯一在按下 Enter 时不会提交表单的浏览器(适用于 FF、Opera、Safari、Chrome 等).我发现这个 javascript 函数试图哄骗 IE 行为；但无济于事:

I have a form with a textbox and a button. IE is the only browser that will not submit the form when Enter is pressed (works in FF, Opera, Safari, Chrome, etc.). I found this javascript function to try to coax IE into behaving; but no avail:

function checkEnter(e){
    var characterCode
    if (e && e.which) {
        e = e
        characterCode = e.which
    } else {
        e = event
        characterCode = e.keyCode
    }
    if (characterCode == 13) {
        document.forms[0].submit()
        return false
    } else {
        return true
    }
}

实施:

searchbox.Attributes("OnKeyUp") = "checkEnter(event)"

有什么建议吗?

此页面在CodeProject 概括了 Dillie 所说的内容，而且效果很好.

推荐答案

我过去做的另一件事是将表单区域包装在 Panel 中，并将 DefaultButton 属性设置为您拥有的提交按钮.只要您在面板区域中有一个表单元素处于焦点位置，这就会有效地将 enter 键映射到提交.

The other thing I have done in the past is wrap the form area in a Panel and set the DefaultButton attribute to the submit button you have. This effectively maps the enter key to the submission as long as you have a form element in focus in the panel area.
