通過Ajax在URL中傳遞變量

Question

這是一段使用jQuery Datatables的JavaScript代碼。

我想通過變量ident（它等於2在下面的例子中）在通過Ajax的URL，見下圖：

ajax: "staff2.php?userid='+ ident +'" 

它不是通過正常。但是用2替代'+ ident +'的作品。

那麼這條線有什麼問題？

var ident = '2'; 


var editor; // use a global for the submit and return data rendering in the examples 
$(document).ready(function() { 
    editor = new $.fn.dataTable.Editor({ 
     ajax: "staff2.php?userid='+ ident +'", 
     table: "#building", 
     "bProcessing": true, 
     "bServerSide": true, 
     fields: [ { 
       label: "", 
       name: "building" 
      } 
     ] 
    }); 
    // Activate an inline edit on click of a table cell 
$('#building').on('click', 'tbody td', function() { 
    editor.inline(this); 
}); 
    $('#building').DataTable({ 
     //dom: "Tfrtip", 
     "searching": false, 
     "bInfo" : false, 
     "bPaginate": false, 
     "bSort": false, 
     "bVisible": false, 
     ajax: "staff2.php?userid='+ ident +'", 
     columns: [ 
      { data: null, defaultContent: '', orderable: false }, 
      { data: "building" },   
     ], 
     order: [ 1, 'asc' ], 
     tableTools: { 
      sRowSelect: "os", 
      sRowSelector: 'td:first-child', 
      aButtons: [ 
       { sExtends: "editor_create", editor: editor }, 
       { sExtends: "editor_edit", editor: editor }, 
       { sExtends: "editor_remove", editor: editor } 
      ] 
     } 
    }); 
}); 

Answer 1

你沒有正確地構建URL。

替換：

ajax: "staff2.php?userid='+ ident +'", 

與

ajax: "staff2.php?userid=" + ident, 

如果ident不僅包含數字，還需要與encodeURIComponent()編碼作爲encodeURIComponent(ident)正確轉義特殊字符。

Answer 2

在字符串連接中出現錯誤。 替換此行：

ajax: "staff2.php?userid='+ ident +'", 

有了這個：

ajax: "staff2.php?userid=" + ident,
