如何防止在基于web的应用程序中按ENTER键提交表单?


当前回答

I Have come across this myself because I have multiple submit buttons with different 'name' values, so that when submitted they do different things on the same php file. The enter / return button breaks this as those values aren't submitted. So I was thinking, does the enter / return button activate the first submit button in the form? That way you could have a 'vanilla' submit button that is either hidden or has a 'name' value that returns the executing php file back to the page with the form in it. Or else a default (hidden) 'name' value that the keypress activates, and the submit buttons overwrite with their own 'name' values. Just a thought.

另一种方法是仅在表单应该提交时才将提交输入按钮附加到表单,并在表单填充期间将其替换为简单的div

我花了一些时间制作这款跨浏览器,适用于IE8、9、10、Opera 9+、Firefox 23、Safari(PC)和Safari(MAC)

示例:http://jsfiddle.net/greatbigmassive/ZyeHe/

基本代码-通过“onkeypress”附加到您的窗体和传递窗口调用此函数。事件”。

function stopEnterSubmitting(e) {
    if (e.keyCode == 13) {
        var src = e.srcElement || e.target;
        if (src.tagName.toLowerCase() != "textarea") {
            if (e.preventDefault) {
                e.preventDefault();
            } else {
                e.returnValue = false;
            }
        }
    }
}

将这个标签添加到你的表单- onsubmit="return false;" 然后只能使用JavaScript函数提交表单。

简单地添加这个属性到你的FORM标签:

onsubmit="return gbCanSubmit;"

然后,在你的SCRIPT标签中,添加这个:

var gbCanSubmit = false;

然后,当你创建一个按钮或出于任何其他原因(比如在函数中)你最终允许提交时,只需翻转全局布尔值并执行.submit()调用,类似于下面的示例:

function submitClick(){

  // error handler code goes here and return false if bad data

  // okay, proceed...
  gbCanSubmit = true;
  $('#myform').submit(); // jQuery example

}
