javascript - ExtJs 数字字段

Question

我正在使用 ExtJs NumberField。好处是它验证只输入了数字。但我也想要一个连字符。我怎么能去编辑 javascript

  var <portlet:namespace/>issueNoField = new Ext.form.NumberField({  //This takes only numbers
             fieldLabel: 'Issue No',
             width: 120,
             displayField: 'Enter no',  
             valueField:'IssNo'
         });

Answer 1

var <portlet:namespace/>issueNoField = new Ext.form.TextField({  //This takes only numbers
  fieldLabel: 'Issue No',
  width: 120,
  regex: /[1-9-]*/
});
