trying to bind enter click to onkeyup event of a field
提问by Neta Meta
So in normal situation where jquery i allowed and i can bind the field onkeyup i would use:
所以在 jquery 我允许的正常情况下，我可以绑定字段 onkeyup 我会使用：
$('#something').keyup(function(e) {
var enterKey = 13;
if (e.which == enterKey){
somefunction();
}
});
however i cannot use this and will have to use something like:
但是我不能使用它，必须使用类似的东西：
<input id="something" onkeyup="onkeyup_colfield_check(this)" type="text">
function onkeyup_colfield_check(e){
var enterKey = 13;
if (e.which == enterKey){
somefunction();
}
}
However this doesn't work like the above.
然而，这不像上面那样工作。
how can i achieve the same result like the first example but with something like that?
我怎样才能获得与第一个示例相同的结果，但使用类似的方法？

You need to pass in eventas an argument, not this.
您需要event作为参数传入，而不是this.
<input id="something" onkeyup="onkeyup_colfield_check(event)" type="text">
Also, to be fully compatible with all major browsers, you may want to use the following for detecting te key code of the key pressed.
此外，为了与所有主要浏览器完全兼容，您可能需要使用以下内容来检测按下的键的键代码。
var charCode = (typeof e.which === "number") ? e.which : e.keyCode;
