jquery validate linkage verification
Originally, our project only had ID cards. But now we need to add a Hong Kong, Macao and Taiwan pass for verification.
That is, you have to choose an identity type before choosing.
Now it will be changed to this. I have to conduct separate verification of the mainland ID card when the user selects the ID card. If you choose Taiwan, I will verify Taiwan separately. All JS validations on the front end of the project are verified using jquery validate. After struggling for a long time, the original
var join_msg = 1; jQuery.validator.addMethod("id_card",function(value,element){ var type = $("#id_type").val(); console.log(type[0].value); if(!type){ join_msg = "请选择身份类型"; return false; } if(type == 1){ join_msg = "身份证不合法"; var CN = isIdCardNo(value); return CN; }else if( type == 2){ } },function(){ return join_msg; } );
was originally a type obtained separately in the verification. However, I felt that this was unreliable, so I added an extra parameter to the addmethod method.
jQuery.validator.addMethod("id_card",function(value,element,type){ console.log(type[0]); },function(){ } ); 规则方面我用的 id_card:{ required: false, id_card: [$("#id_type").val()] },
But no matter how I pass the parameters to the addmethod method, The type parameter in is always empty. No matter how much I try, I can't get it. In the background, I changed the rules
id_type:{ required: true }, id_card:{ required: false, id_card: [id_type] },
, which is the id_card. What is actually passed is the id_type above, which is this form element. This is handled in addmethod reception
var join_msg = "请填写正确的证件号码和选择正确的身份类型"; jQuery.validator.addMethod("id_card",function(value,element,type){ var new_type = type[0].value; console.log(new_type); if(!new_type){ join_msg = "请选择身份类型"; return this.optional(element) || false; } if(new_type == 1){ join_msg = "身份证不合法"; var CN = isIdCardNo(value); return this.optional(element) || CN; }else if(new_type == 2){ } },function(){ return join_msg; } );
This way I can judge whether different ID numbers are correct based on different identity types. The front-end judgment is correct and it is easier for my back-end to process.
See the results:
Verified successfully and correctly. And there are different tips.

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

There is no absolute salary for Python and JavaScript developers, depending on skills and industry needs. 1. Python may be paid more in data science and machine learning. 2. JavaScript has great demand in front-end and full-stack development, and its salary is also considerable. 3. Influencing factors include experience, geographical location, company size and specific skills.

Learning JavaScript is not difficult, but it is challenging. 1) Understand basic concepts such as variables, data types, functions, etc. 2) Master asynchronous programming and implement it through event loops. 3) Use DOM operations and Promise to handle asynchronous requests. 4) Avoid common mistakes and use debugging techniques. 5) Optimize performance and follow best practices.
