我编写了一个 jquery 脚本，它会自动检测用户输入的号码。如果用户输入了 2,4,6,8,10 - 他们将自动弹出一个确认框，说明有报价。

如果他们单击“是”，他们将被重定向。但是，如果他们单击“取消”，它会重新聚焦在文本框上，并且再次出现确认框。

无论如何我可以做到，所以如果用户点击取消，焦点不在文本框上，所以不会出现确认框循环。

HTML

<input type="text" class="Quantity" id="Quantity9438851" name="Quantity" value="1" style="width:30px">

查询

$("#Quantity9438851").bind("change paste keyup", function() {
    if($(this).val() == 2){
     var didConfirm = confirm("There is currently an offer for 2 polo shirt for £25. Click YES to recieve discount.");
      if (didConfirm == true) {
        window.location.href = "http://blahblah.com/&Quantity=10";
      }
    }else if($(this).val() == 4){
     var didConfirm = confirm("There is currently an offer for 4 polo shirt for £50. Click YES to recieve discount.");
      if (didConfirm == true) {
        window.location.href = "http://google.com/Registration/blah";
      }        
    }else if($(this).val() == 6){
     var didConfirm = confirm("There is currently an offer for 6 polo shirt for £75. Click YES to recieve discount.");
      if (didConfirm == true) {
        window.location.href = "http://google.com/Registration/blah";
      }                
    }else if($(this).val() == 8){
     var didConfirm = confirm("There is currently an offer for 8 polo shirt for £100. Click YES to recieve discount.");
      if (didConfirm == true) {
        window.location.href = "http://google.com/Registration/blah";
      }                
    }else if($(this).val() == 10){
     var didConfirm = confirm("There is currently an offer for 10 polo shirt for £100. Click YES to recieve discount.");
      if (didConfirm == true) {
        window.location.href = "http://google.com/Registration/blah";
      }

为什么不简单地使用blur事件？

$("#Quantity9438851").bind("blur", function() {

    var val = $(this).val();

    if(!(val % 2) && val <= 10){

      var conf = confirm("There is currently an offer for "
         + val +" polo shirt for £25. Click YES to recieve discount.");

      if (conf) 
        window.location.href = "http://google.com/&Quantity=10";


    }
});
