如何使用 jQuery DataTables 发布整个表的数据 [英] How to post data for the whole table using jQuery DataTables

问题描述

我有一个使用 jQuery DataTables 和分页的表格

I have a table working with jQuery DataTables and pagination

我有超过 300 个注册表，其中每页最多 50 个.每次我从一个页面切换到另一个页面时，其他 250 个注册表都会从 DOM 中删除，所以当我提交并执行 POST 到我的控制器时，我只会得到一个包含 50 个模型的列表，这些模型是我当前页面上的模型.

I have over 300 registrys which 50 are the max on each page. Every time I change from page to page the other 250 registrys are removed from DOM so when I submit and do the POST to my controller I only get a list of 50 models which are the ones on my current page.

我如何访问其他 250 个，或告诉表将它们全部发送?我已经搜索过并且读到这是分页的正常行为.但是你们是如何解决这个问题的?

How do I access the other 250, or tell the table to send them all? I have searched and I have read that this is the normal behavior of pagination. But how do you guys work around it?

推荐答案

CAUSE

当使用带有分页的 DataTables 插件时，为了性能和兼容性，DOM 中仅存在当前页面行.因此，当您提交表单时，只会提交当前页面表单控件值.

CAUSE

When using DataTables plug-in with pagination only current page rows exist in the DOM for performance and compatibility. Therefore when you submit the form, only current page form controls values are being submitted.

诀窍是在提交表单之前将当前页面以外的表单元素转换为 .

The trick is to turn form elements from pages other than current into <input type="hidden"> before submitting the form.

var table = $('#example').DataTable();

// Handle form submission event
$('#frm-example').on('submit', function(e){
   var form = this;

   // Encode a set of form elements from all pages as an array of names and values
   var params = table.$('input,select,textarea').serializeArray();

   // Iterate over all form elements
   $.each(params, function(){
      // If element doesn't exist in DOM
      if(!$.contains(document, form[this.name])){
         // Create a hidden element
         $(form).append(
            $('<input>')
               .attr('type', 'hidden')
               .attr('name', this.name)
               .val(this.value)
         );
      }
   });
});

另一种解决方案是通过 Ajax 提交表单.

Another solution is to submit the form via Ajax.

var table = $('#example').DataTable();

// Handle form submission event
$('#frm-example').on('submit', function(e){
   // Prevent actual form submission
   e.preventDefault();

   // Serialize form data
   var data = table.$('input,select,textarea').serialize();

   // Submit form data via Ajax
   $.ajax({
      url: '/echo/jsonp/',
      data: data,
      success: function(data){
         console.log('Server response', data);
      }
   });
});

请注意，这两种解决方案都只能在客户端处理模式下工作.

Please note that both solutions will work in client-side processing mode only.
