如何选择所有行的HTML表 [英] How to select all rows HTML table

问题描述

我遇到了一个我自己无法解决的问题！

I came across a problem which I can't solve on my own!

我有一个使用PHP/MySQL填充的表

I have a Table which is populated using PHP/MySQL something like

foreach($users as $user){
    ?> <tr id="<?php echo $user['fName'].
            "-".$user['lName'];?>">
        <td> <?php 
            echo $user['fName']." ".$user['lName']; 
        ?> </td>
       <?php 
            for ($i = 0; $i<$count+3; $i++){
                ?> <td><input class="accessCheck" id="<?php
                echo $user['lName']."-".$pagesArray[$i];
                ?>" type="checkbox"></td> 
      <?php } ?>
   </tr> <?php 
}

如您所见，表格看起来像

As you can see table would look something like

fName lName | checkbox | checkbox | checkbox | mainCheckbox 

我需要做的是使用mainCheckbox选中/取消选中所有复选框，是否有一种方法可以仅通过选中该mainCheckbox来选择所有行?

What I need to do is to check/uncheck all checkboxes with mainCheckbox, is there a way to select all rows just from checking this mainCheckbox?

当您选择输入之类的东西时如何找到班级，有没有办法为此找到班级?例如

How to find class when you select something like input, is there a way of finding a class for this? For example

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

});

有没有办法为此输入找到一个类?

Is there a way to find a class for this input?

推荐答案

此:

$('#all').on('click', function(){
    $(':checkbox').prop("checked",$(this).is(':checked'));
});
