Jquery提交不起作用

Jquery提交不起作用

本文介绍了ajax分页后,Jquery提交不起作用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我使用的ajax分页脚本运行正常 -



在第一页上,一切都很好,每个页面上都有提交按钮(多个表单),通过jquery POST将数据发送到数据库。 / p>

但是,jquery帖子仅适用于加载的第一页上的表单/按钮。如果你切换到分页上的另一个页面jquery post / submit按钮不起作用。



任何建议都会非常感激,似乎无法弄明白。



代码段:



分页脚本

 < script> 
$(document).ready(function(){
$(#Pagination)。trigger('setPage',[<?php echo $ member_Program_Week_calc;?>]);
});
< / script>

< script type =text / javascript>
函数pageselectCallback(page_index,jq){
var new_content = jQuery('#hiddenresult div.result:eq('+ page_index +')')。clone();
$('#Searchresult')。empty()。append(new_content);
返回false;
}

函数initPagination(){
//计算隐藏内容中的条目
var num_entries = jQuery('#hiddenresult div.result')。length;
//在分页元素内创建内容
$(#Pagination)。分页(num_entries,{
回调:pageselectCallback,
items_per_page:1 //每个只展示一个项目第$
});
}

//当文档准备就绪时,初始化分页
$(文档).ready(function(){
initPagination();
} );
< / script>

ajaxSubmit函数

 < script type =text / javascript> 
$(document).ready(function(){

$('#completetask_<?php the_sub_field('tasks_id');?>')。submit(ajaxSubmit); / / example

函数ajaxSubmit(){

$(this).find(':submit')。attr('disabled','disabled');

var completetask = jQuery(this).serialize();

jQuery.ajax({
type:POST,
url:/ wp- admin / admin-ajax.php,
data:completetask,
success:function(data){
jQuery(#feedback)。html(data);
} ,
错误:function(errorThrown){
alert(errorThrown);
}
});
返回false;
}
} );
< / script>

表格代码

 < form method =postid =completetask_<?php echo $ task_id;?>> 
< input type =hiddenname =program_idid =program_idvalue =<?php echo $ program_id;?>/>
< input type =hiddenname =session_idid =session_idvalue =<?php echo $ session_id;?>/>
< input type =hiddenname =task_idid =task_idvalue =<?php echo $ task_id;?>/>
< input type =hiddenname =actionvalue =completeTask/>

< input class =program_task_submit_no program_task_submit_no_<?php echo $ task_id;?> type =submitvalue =COMPLETE TASK/>

< / form>


解决方案

由于建议,我设法解决了这个问题来自@charlietfl并进行了一些进一步的研究。



解决方案是事件委托,使用.on()函数。



使用我的代码,我使用.on函数更改了ajaxSubmit函数代码。



简单示例:

  $(document).on('submit','#completetask',function(e){
// CODE
});

我更新的代码:

  $(document).on('submit','#completetask_<?php the_sub_field('tasks_id');?>',function(e){

$(this).find(':submit')。attr('disabled','disabled');

var completetask = jQuery(this).serialize();

var css = document.createElement(style);
css.type =text / css;
css.innerHTML =。program_task_title_<?php the_sub_field( 'tasks_id');?> {color:green!important;};

document.body.appendChild(css);

jQuery.ajax({
类型:POST,
url:/ wp-admin / admin-ajax.php,
数据:completetask,
成功:函数(数据){
jQuery(#feedback)。html(data);
},
error:function(errorThrown){
alert(errorThrown);
}
}) ;
返回false;

});

我删除了原始的ajaxSubmit功能代码。



使用CSS



我还需要在提交按钮后执行CSS,这样就改变了表单的样式。但是,将页面重置更改为正常。为了解决这个问题,我在脚本中执行了CSS样式。

  var css = document.createElement(style); 
css.type =text / css;
css.innerHTML =。program_task_title_<?php the_sub_field('tasks_id');?> {color:green!important;};

document.body.appendChild(css);

谢谢。


I am using an ajax pagination script which works fine - https://github.com/gbirke/jquery_pagination

On the first page everything works great, there are submit buttons (multiple forms) on each page, which send data to the database via a jquery POST.

However, the jquery post only works for forms/buttons on the first page that is loaded. If you switch to another page on the pagination the jquery post / submit button does not work.

Any suggestions would be much appreciated, can't seem to figure it out.

Code snippets:

Pagination Scripts

<script>
    $(document).ready(function() {
        $("#Pagination").trigger('setPage', [<?php echo $member_Program_Week_calc; ?>]);
    });
</script>

 <script type="text/javascript">
    function pageselectCallback(page_index, jq){
        var new_content = jQuery('#hiddenresult div.result:eq('+page_index+')').clone();
        $('#Searchresult').empty().append(new_content);
        return false;
    }

    function initPagination() {
        // count entries inside the hidden content
        var num_entries = jQuery('#hiddenresult div.result').length;
        // Create content inside pagination element
        $("#Pagination").pagination(num_entries, {
            callback: pageselectCallback,
            items_per_page:1 // Show only one item per page
        });
     }

    // When document is ready, initialize pagination
    $(document).ready(function(){
        initPagination();
    });
 </script>

ajaxSubmit function

<script type="text/javascript">
$(document).ready(function() {

    $('#completetask_<?php the_sub_field('tasks_id'); ?>').submit(ajaxSubmit); // example

        function ajaxSubmit(){

                $(this).find(':submit').attr('disabled','disabled');

                var completetask = jQuery(this).serialize();

                jQuery.ajax({
                        type:"POST",
                        url: "/wp-admin/admin-ajax.php",
                        data: completetask,
                        success:function(data){
                jQuery("#feedback").html(data);
                        },
                error: function(errorThrown){
                    alert(errorThrown);
                }
                });
                return false;
        }
    });
</script>

Form Code

<form method="post" id="completetask_<?php echo $task_id; ?>">
    <input type="hidden" name="program_id" id="program_id" value="<?php echo $program_id; ?>"/>
    <input type="hidden" name="session_id" id="session_id" value="<?php echo $session_id; ?>"/>
    <input type="hidden" name="task_id" id="task_id" value="<?php echo $task_id; ?>"/>
    <input type="hidden" name="action" value="completeTask"/>

        <input class="program_task_submit_no program_task_submit_no_<?php echo $task_id; ?>" type="submit" value="COMPLETE TASK"/>

</form>
解决方案

I've managed to solve this thanks to a suggestion from @charlietfl and a little further research.

The solution is event delegation, using the .on() function.

With my code, I changed the ajaxSubmit function code around using the .on function.

Simple Example:

$(document).on('submit', '#completetask', function(e) {
    //CODE
});

My Updated Code:

$(document).on('submit', '#completetask_<?php the_sub_field('tasks_id'); ?>', function(e) {

    $(this).find(':submit').attr('disabled','disabled');

    var completetask = jQuery(this).serialize();

    var css = document.createElement("style");
    css.type = "text/css";
    css.innerHTML = ".program_task_title_<?php the_sub_field('tasks_id'); ?> { color: green !important; }";

    document.body.appendChild(css);

    jQuery.ajax({
            type:"POST",
            url: "/wp-admin/admin-ajax.php",
            data: completetask,
            success:function(data){
    jQuery("#feedback").html(data);
            },
    error: function(errorThrown){
        alert(errorThrown);
    }
    });
    return false;

});

I removed the original ajaxSubmit function code.

Working with CSS

I also needed CSS to execute once the button is submit which changed the style of the form. However, changing page reset this back to normal. In order to solve this I executed CSS styling within the script.

var css = document.createElement("style");
css.type = "text/css";
css.innerHTML = ".program_task_title_<?php the_sub_field('tasks_id'); ?> { color: green !important; }";

document.body.appendChild(css);

Thanks.
