推荐答案

使用带有或条件(用于小数点)的键代码110.

Use key code 110 with OR condition which is for decimal point.

您可以使用onkeydown或onkeypress事件捕获事件键代码，然后按Tab键代码.

在文本框中尝试这样的操作:

You can use onkeydown or onkeypress event to trap the event keycode and then press tab keycode.

Try something like this for the textbox:

<input type="text" onkeydown="EnterToTab()">

JS代码:

JS code:

function EnterToTab(){
  if (event.keyCode==110)
    event.keyCode=9;
  }

从此处选择适当的键码: JavaScript字符码(键码) [ ^ ]-看起来像根据您的情况而定为110.

PS:这是不建议使用的，因为Enter和Tab具有两个不同的功能来执行和使用它们，这并不是很好.

Pick the appropriate keycode from here: Javascript Char Codes (Key Codes)[^] - Looks like it''s 110 for your case.

PS: This is not suggestible as Enter and Tab have two different functions to perform and playing with them like this not good.
