JavaScript / jQuery VIN Validator [英] JavaScript/jQuery VIN Validator

问题描述

有没有人创建过VIN验证程序？我试图创建一个文本框，用户将输入车辆标识号，然后JS / jQuery将验证如果其正确或不，如果他们键入数字。

我对JS / jQuery非常新，已经找到了一些例子，但是当然没能让他们正常工作...任何一个有任何想法或建议，将非常感谢，特别是如果你可以告诉我如何设置我下面的工作正常！

注意： isVin（）函数由 cflib.org

HTML：

 < label name =vin> VIN< / label> 
< input type =textname =vin/> 
  

ColdFusion：

测试代码：

 < cfoutput> 
< cfset vin =1GNDM19ZXRB170064> 
＃vin＃：#isVin（vin）＃< br /> 
< cfset vin =1FAFP40634F172825> 
＃vin＃：#isVin（vin）＃< br /> 
< / cfoutput> 
  

解决方案

这里是一个使用正则表达式的客户端解决方案。 / p>

 < script src =https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js>< / script>< label name =vin> VIN< / label> ;< input type =textid =vinvalue =1FAFP40634F172825/>< span id =result>< / span>  

Has anyone ever created a VIN Validator? I am trying to create a textbox where the user will enter in a Vehicle Identification Number and then JS/jQuery will validate if its correct or not in case they mistype the number.

I am very new to JS/jQuery and have found some examples but of course have not been able to get them to work correctly... Any one with any ideas or suggestions it would be greatly appreciated, especially if you can tell me how to set up what I have below to work properly!

Note: The isVin() function is courtesy of cflib.org

HTML:

<label name="vin">VIN</label>
<input type="text" name="vin" />

ColdFusion:

解决方案

Here's a client-side solution using Regular Expressions.

$(function() {
  $("#vin").on("keyup blur", function() {
    if (validateVin($("#vin").val()))
      $("#result").html("That's a VIN");
    else
      $("#result").html("Not a VIN");
  });
});
  
function validateVin(vin) {
  var re = new RegExp("^[A-HJ-NPR-Z\\d]{8}[\\dX][A-HJ-NPR-Z\\d]{2}\\d{6}$");
  return vin.match(re);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<label name="vin">VIN</label>
<input type="text" id="vin" value="1FAFP40634F172825" />
<span id="result"></span>
