使用Javascript的电话格式在Firefox中不起作用 [英] Phone Format using Javascript is not working in Firefox

问题描述

我正在使用以下功能来自动设置电话号码格式.它在除Firefox之外的其他浏览器中运行良好.请任何人告诉我为什么它不能在Firefox中运行.

I am using the following function for auto format of phone numbers. It is working good in other browsers except Firefox. Please can any body tell me why it is not working in Firefox.

function FormatPhone()
       {

           if( ((window.event.keyCode >= 97) && (window.event.keyCode <= 122)) || ((window.event.keyCode >= 65) && (window.event.keyCode <= 90)) )
           {
               return false;
           }
           else
           {
               if (event.keyCode == 8 || event.keyCode==37)
               {
                   return;
               }

               phone = event.srcElement.value;
               if (phone.length==1 && phone != "(")
               {
                   event.srcElement.value = "(" + phone;
               }
               else if (phone.length==4 && phone.substring(0,1) == "(" && ! isNaN(phone.substring(1,4)))
               {
                   event.srcElement.value = phone + ") ";
               }
               else if (phone.length==9 && phone.substring(0,1) == "(" && ! isNaN(phone.substring(1,4)) && phone.substring(4,5) == ")" && ! isNaN(phone.substring(6,9)))
               {
                   event.srcElement.value = phone + "-";
               }
           }
       }

我在page_load中调用此函数

I am calling this function in the page_load

txtPhone2.Attributes.Add("Onkeypress", "return FormatPhone()");

非常感谢，

推荐答案

我已经使用以下代码解决了这个问题...

I have solved this problem with the below code...

function FormatPhone(e) {
            evt = e || window.event;
            var keyPressed = evt.which || evt.keyCode;

            if(((keyPressed >= 97) && (keyPressed <= 122)) || ((keyPressed >= 65) && (keyPressed <= 90))) {
                return false;
            }
            else {
                if (keyPressed == 8 || keyPressed == 37) {
                    return;
                }

                var target = evt.target || evt.srcElement;

                phone = target.value;
                if (phone.length == 1 && phone != "(") {
                    target.value = "(" + phone;
                }
                else if (phone.length == 4 && phone.substring(0, 1) == "(" && !isNaN(phone.substring(1, 4))) {
                    target.value = phone + ") ";
                }
                else if (phone.length == 9 && phone.substring(0, 1) == "(" && !isNaN(phone.substring(1, 4)) && phone.substring(4, 5) == ")" && !isNaN(phone.substring(6, 9))) {
                    target.value = phone + "-";
                }
            }
        }

并在page_load

and passing the event in the page_load

txtPhone2.Attributes.Add("Onkeypress", "return FormatPhone(event)");

中传递事件
