我使用PHP，jQuery的，AJAX，Smarty的为我的网站。我在从Smarty的模板下面这行code。我婉呼吁该超链接的onclick jQuery的AJAX功能，但我不能调用它。你能帮我到jQuery的AJAX功能，给予电话吗？ 以下是我的code。 从Smarty的模板code：

I'm using PHP, jQuery, AJAX, Smarty for my website. I'm having following line of code from smarty template. I wan to call the jQuery AJAX function on the onclick of that hyperlink but I'm not able to call it. Can you help me in giving call to the jQuery AJAX function? Following is my code. Code from Smarty template:

<a class="edit_user_transaction_status" href="{$control_url}{$query_path}?op=edit_user_transaction&page={$page}&txn_no={$user_transaction_details.transaction_no}&transaction_data_assign={$user_transaction_details.transaction_data_assign}&user_id={$user_id}{if $user_name!=''}&user_name={$user_name}{/if}{if $user_email_id!=''}&user_email_id={$user_email_id}{/if}{if $user_group!=''}&user_group={$user_group}&{/if}{if $user_sub_group!=''}&user_sub_group={$user_sub_group}{/if}{if $from_date!=''}&from_date={$from_date}{/if}{if $to_date!=''}&to_date={$to_date}{/if}{if $transaction_status!=''}&transaction_status={$transaction_status}{/if}{if $transaction_no!=''}&transaction_no={$transaction_no}{/if}">Update</a>

的jQuery AJAX的功能如下：

jQuery AJAX function is as follows:

$(".edit_user_transaction_status").click(function(e) { 
         e.preventDefault();
         //for confirmation that status change
         var ans=confirm("Are you sure to change status?");
         if(!ans) {
             return false;
         }  
         var post_url           = $(this).attr('href');
         var transaction_status_update = $('#transaction_status_update').val();      

         $.ajax({
             type: "POST",
             url: post_url+"&transaction_status_update="+transaction_status_update,
                 data:$('#transaction_form').serialize(),
             dataType: 'json',  
             success: function(data) {              
                 var error = data.login_error;

                 $(".ui-widget-content").dialog("close");
                //This variables use for display title and success massage of transaction update              
                 var dialog_title   = data.title;              
                 var dialog_message = data.success_massage; 
                 //This get link where want to rerdirect
                 var redirect_link  = data.href;            

                 var $dialog = $("<div class='ui-state-success'></div>")
                 .html("<p class='ui-state-error-success'>"+dialog_message+"</p>")
                 .dialog({
                     autoOpen: false,
                     modal:true,
                     title: dialog_title,
                     width: 500,
                     height: 80,
                     close: function(){                                     
                         document.location.href =redirect_link;
                     }                  
                 });                    

                 $dialog.dialog('open');                    
             }          
        });
     });
});

如果我试图在功能它没有得到印开始打印警报。你能帮我实现吗？先谢谢了。

If I try to print the alert at the beginning of function it's not getting printed. Can you help me in achieving this? Thanks in advance.

修正code：

$(".edit_user_transaction_status").click(function(e) { 
         e.preventDefault();
         //for confirmation that status change
         var ans=confirm("Are you sure to change status?");
         if(!ans) {
             return false;
         }  
         var post_url           = $(this).attr('href');
         var transaction_status_update = $('#transaction_status_update').val();      

         $.ajax({
             type: "POST",
             url: post_url+"&transaction_status_update="+transaction_status_update,
                 data:$('#transaction_form').serialize(),
             dataType: 'json',  
             success: function(data) {              
                 var error = data.login_error;

                 $(".ui-widget-content").dialog("close");
                //This variables use for display title and success massage of transaction update              
                 var dialog_title   = data.title;              
                 var dialog_message = data.success_massage; 
                 //This get link where want to rerdirect
                 var redirect_link  = data.href;            

                 var $dialog = $("<div class='ui-state-success'></div>")
                 .html("<p class='ui-state-error-success'>"+dialog_message+"</p>")
                 .dialog({
                     autoOpen: false,
                     modal:true,
                     title: dialog_title,
                     width: 500,
                     height: 80,
                     close: function(){                                     
                         document.location.href =redirect_link;
                     }                  
                 });                    

                 $dialog.dialog('open');                    
             }          
        });
     });
