自动保存你可以确认用户输入完成后把数据存在local storage

你可以给每个字段绑定一个onchange事件触发保存草稿，或者间隔固定时间执行一次保存草稿。你只能做到自动保存草稿，不可能自动提交表单的，所有的校验都符合不证明填表人的也认为内容不需要修改。

这个可以两种方法：
1、本地localstorage，可是这种办法低版本ie无效；
2、服务端做session存储，每一个步骤请求一次网络，存储服务端就可以

Html5 localstorage

How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

What are the characteristics of do-while loops in PHP?May 15, 2025 pm 08:57 PM

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

How to hash strings in PHP?May 15, 2025 pm 08:54 PM

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

How to implement array sliding window in PHP?May 15, 2025 pm 08:51 PM

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

How to use the __clone method in PHP?May 15, 2025 pm 08:48 PM

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

How to use goto statements in PHP?May 15, 2025 pm 08:45 PM

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements. Overall, goto should be used with caution and best practices are followed to ensure the readability and maintainability of the code.

How to implement data statistics in PHP?May 15, 2025 pm 08:42 PM

In PHP, data statistics can be achieved by using built-in functions, custom functions, and third-party libraries. 1) Use built-in functions such as array_sum() and count() to perform basic statistics. 2) Write custom functions to calculate complex statistics such as medians. 3) Use the PHP-ML library to perform advanced statistical analysis. Through these methods, data statistics can be performed efficiently.

How to use anonymous functions in PHP?May 15, 2025 pm 08:39 PM
