ExtJs NumberField
提问by Some Java Guy
I am using ExtJs NumberField. The good thing is it validates that only numbers are entered. But I want a hyphen as well. How could I go about editing the javascript

fieldLabel: 'Issue No',

displayField: 'Enter no',
valueField:'IssNo'
});

Use "baseChars" option.
使用“baseChars”选项。
var <portlet:namespace/>issueNoField = new Ext.form.NumberField({ //This takes only numbers
fieldLabel: 'Issue No',
width: 120,
displayField: 'Enter no',
valueField:'IssNo'
baseChars: "0123456789-"
});

Is the hyphen merely conventional, as in a US zip code (99999-9999)? In that case, you should accept only numeric input, insert the hyphen when that position is reached, and ignore any non-numeric characters.
连字符是否只是常规的，如美国邮政编码 (99999-9999)？在这种情况下，您应该只接受数字输入，到达该位置时插入连字符，并忽略任何非数字字符。
If they hyphen is significant, so that "12-345" and "123-45" are different inputs, then you are reading text and not a number. However, that would be an extremely unfriendly system.
如果它们的连字符很重要，因此“12-345”和“123-45”是不同的输入，那么您正在阅读文本而不是数字。然而，这将是一个非常不友好的系统。

The Regex attribute never worked for me, I used the code below instead:
Regex 属性从来没有对我有用，我改用下面的代码：
maskRe: /[1-9-]/,
回答by BhandariS
{
xtype: 'textfield',
mask: '(999) 999-9999'
}
What I'm proposing here is that we use a text fieldand put a mask to it to capture only numeric values in the desires format.
我在这里提议的是，我们使用 atext field并为其放置一个掩码，以仅捕获所需格式的数字值。
You can mask it according to your needs.
您可以根据需要对其进行屏蔽。
For Example:
例如：
'9999999999'
'999-999-9999'

Just set the allowExponentialconfig of your numberfield to false. By default it is true and it adds 'e+-'and the decimalSeparatoras valid characters.
只需将allowExponentialnumberfield的配置设置为 false。默认情况下它是 true 并且它添加'e+-'和decimalSeparator作为有效字符。
It's true. The source check the source.
这是真的。来源检查来源。
