使用多个输入框按“输入" [英] Pressing 'enter' with multiple input boxes
问题描述
我有一个HTML表单，其中包含几个输入框和它们相应的输入按钮.当我在第一个输入框中键入内容并按 Enter 或按钮时，它可以正常工作.但是，如果我在其他框中按 Enter ，则它就像在第一个框中一样.按钮工作正常.
I have an HTML form with several input boxes and their corresponding enter button. When I type something in the first input box and either press Enter or the button, it works fine. But if I press Enter in the other boxes it works as if it was in the first box. The buttons work OK.
这是我的代码:
<script type="text/javascript">
function fn (num) {
alert(num);
document.getElementById(num).focus();
}
</script>
</head>
<body>
<form>
<input id="1" type="text"></input> <button onclick="fn(1);">press</button><br/>
<input id="2" type="text"></input> <button onclick="fn(2);">press</button><br/>
<input id="3" type="text"></input> <button onclick="fn(3);">press</button><br/>
</form>
显然，这是ECMA中的一个怪胎"(我已经在FF18.0.1和Safari 5.1.7中进行了测试). 这个怪癖有解决方法吗?
Apparently this is a 'quirk' in ECMA (I have tested in FF18.0.1 and Safari 5.1.7). Is there a fix for this quirk?
我发现的一种解决方案是在每个输入框中添加一个表单.
One solution that I found is to add one form per input box.
<form>
<input id="1" type="text"></input> <button onclick="fn(1);">press</button><br/>
</form>
<form>
<input id="2" type="text"></input> <button onclick="fn(2);">press</button><br/>
</form>
<form>
<input id="3" type="text"></input> <button onclick="fn(3);">press</button><br/>
</form>
这是错误还是功能?有更好的解决方案吗? 感谢您的任何建议.
Is this a bug or a feature? Is there a better solution? Thanks for any suggestions.
推荐答案
您将要使用onKeyPress而不是onClick.试试这个:
You'll want to use onKeyPress instead of onClick. Try this:
function myKeyPress(args) {
if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) {
// do something here (enter has been pressed)
}
else {
return false; // somehow prevents "default" form behaviors
}
}
