如何使用JS / Jquery清除div容器的内容？ [英] How to clear content of div container using JS/Jquery?

问题描述

我一直在开发一些页面，我需要清除一些div的内容：

I have been developing some page and I need to clear a content of some div:

                <table>
                    <tbody>
                    <div class="records_content">
                        <?php
                            $i=0;
                            foreach ($records as $record) {
                                echo "<tr class = 'output' style='border-bottom: 1px dotted silver;'>";
                                echo "<td width='400'>" . strip_tags($record['language_value']) . "</td>";
                                if ($record['approved_translation'])
                                {
                                    echo "<td width='200' height='30'><div class='field' id='".$record['label_value']."/".$record['language_id']."'>".
                                        strip_tags($record['approved_translation']['language_value'])."</div></td><td><button class='btn btn-info' id='{$record['label_value']}/{$record['language_id']}' href='#'>More...</button>"."</td>";
                                }
                                else
                                {
                                    echo "<td  width='200'>"."<div id='".$record['label_value']."/".$record['language_id']."'><span class='no_translate'>Not translated</span></div>" . "</td>";   
                                }                   
                                echo '</tr>';
                                $i++;
                            }
                        ?>
                    </div>
                    </tbody>
                </table> 

一段JS代码：

           $(".page_button").click(function () {
                $.post("http://"+document.location.host+"/index.php/welcome/update_records_set/"+this.id,
                    function(data)
                    {
                        alert('123');
                        $(".records_content").empty();
                    });
            });

这个脚本有效，因为我看到'123'通知，但div容器有'.records_content'类目前尚不清楚。请告诉我，我该如何解决？谢谢。

This script works, because I see '123' notification, but div container with '.records_content' class isn't clear. Please, tell me, how can I fix it? Thank you.

更新：
现在可行。但是我有一个新的分页问题：

UPDATE: Now it works. But I have a new problem with pagination:

                <br><b>Page:</b><br/>
                <?php
                    for($i=0; $i<$count; $i++)
                    {
                        if ($i==0)
                        {
                            echo "<div class='selected_page_button'>".($i+1)." "."</div>";
                        }
                        else
                        {
                            echo "<div class='page_button'>".($i+1)." "."</div>";
                        }
                    }
                ?>

更改按钮类别的代码：

                $(".page_button").click(function () {

                    $(".selected_page_button").attr("class", "page_button");
                    $(this).attr("class", "selected_page_button");
                });

它可以在没有第一个按钮的情况下正常运行。创建页面后，将选择第一页。当我点击2时，1很简单，选择2。所有按钮都没有1同样的事情：如果我点击2（或其他），那么我不能先点击！ 1更改了它的视图但不改变行为，因为简单按钮是可点击的，所选按钮不可点击！

It works correctly for all buttons without first. When my page is created the first page is selected. When I click by "2", then "1" is simple and "2" is selected. The same thing is with all buttons without "1": if I click by "2" (or other one) then I can't click by first! "1" changes it's view but doesn't change behavior, because simple button is clickable and selected button is not clickable!

推荐答案

确实使用 .empty（）作为你的代码状态，除了在警报后清除。请参阅此处： http://jsfiddle.net/YPLeB/

It does clear using .empty() as your code already states, except that it clears after the alert. See here: http://jsfiddle.net/YPLeB/

单击确定后， DIV 将按预期清除。

After you click "OK", the DIV is cleared as expected.
