防止enter进入textarea

Question

I want to allow the user to press enter and save the text of the textarea, but I want the newline NOT to get applied in the text of the textarea. Is that possible?

这是我的jsFiddle。

e.stopPropagation();

好像还不够！

Answer 1

你要找的是e.preventDefault()。停止传播只是停止在 DOM 树中冒泡。

Answer 2

我刚刚在 JSFiddle 中尝试了这段代码，对我来说效果很好

$('textarea').keypress(function(event) {
   if (event.keyCode == 10 || event.keyCode == 13) {
     event.preventDefault();
   }
});

Answer 3

你错过了 return false;。

尝试here。

Answer 4

试试这个：

$('#cagetextbox').keypress(function(e){return CancelNewLine(e);});

function CancelNewLine(e)
{
    var keynum;
    if(window.event) // IE
        keynum = e.keyCode;
    else if(e.which) // Netscape/Firefox/Opera
        keynum = e.which; 

    return (keynum != 13);
}
