（php / jquery）根据另一个选中的复选框值隐藏和显示复选框
[英](php/jquery) hide and show checkboxes according to another checked checkbox value
问题描述
i have a table in my database like this: 
我在数据库中有一个这样的表：
------------------------------
| ID_1 | ID_2 |
------------------------------
| A | 1 |
| A | 2 |
| A | 3 |
| B | 1 |
| B | 2 |
| B | 5 |
| C | 1 |
| C | 4 |
| C | 3 |
------------------------------
and i have some checkboxes for ID_1 like this 我有一些ID_1的复选框，像这样
<input class="ID_1" type="checkbox" value="A">
<input class="ID_1" type="checkbox" value="B">
<input class="ID_1" type="checkbox" value="C">
i'm trying to do that each time i checked the ID_1 checkbox, the ID_2 checkbox will show, depends on ID_1 checkbox i checked according to the table above. 我每次尝试选中ID_1复选框时都会尝试执行此操作，ID_2复选框将显示，具体取决于我根据上表选中的ID_1复选框。 so if i checked two checkboxes 因此，如果我选中两个复选框
<input class="ID_1" type="checkbox" value="A" checked>
<input class="ID_1" type="checkbox" value="B" checked>
<input class="ID_1" type="checkbox" value="C">
it'll show like this: 它会显示如下：
<input class="ID_2" type="checkbox" value="1">
<input class="ID_2" type="checkbox" value="2">
<input class="ID_2" type="checkbox" value="3">
<input class="ID_2" type="checkbox" value="5">

This is possible using jquery, you need to display all the checkboxes and use class instead of Id. 使用jquery可以做到这一点，您需要显示所有复选框并使用class代替Id。 I am working on a solution will post once done. 我正在研究的解决方案将在完成后发布。
Here is working solution for you. 这是适合您的解决方案。 You can just add this in a script and run in browser. 您可以将其添加到脚本中并在浏览器中运行。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <!DOCTYPE html > <html> <head> <script src="javas/jquery-1.12.2.min.js" type="text/javascript"></script> <script type="text/javascript"> $('document').ready(function () { //OBJECT OF ARRAY WITH YOUR DESIRED VALUES FROM DATABASE, THIS COULD BE MADE DYNAMICALLY var id1Obj = { A:['1','2','3'], B:['1','2','5'], C:['1','3','4'] }; $('.ID_1').click(function () { $('.ID_2').hide(); jQuery('.ID_1:checked').each(function( index ) { var valId1CheckboxVal = $(this).val(); jQuery('.ID_2').each(function( index ) { if( $.inArray( $( this ).val(), id1Obj[valId1CheckboxVal] ) != -1 ) { $(this).show(); } else { // console.info("flse for " + $( this ).val()); // console.log( $(this) ); } }); }); }); }); </script> </head> <body> <div style="width:100%"> <label>ID_1 checkboxes</label><br> <input class="ID_1" type="checkbox" value="A"> A<br> <input class="ID_1" type="checkbox" value="B"> B<br> <input class="ID_1" type="checkbox" value="C"> C<br> <br> </div> <br> <div style="width:100%"> <label>ID_2 checkboxes</label><br> <input class="ID_2" type="checkbox" value="1">1 <br> <input class="ID_2" type="checkbox" value="2">2 <br> <input class="ID_2" type="checkbox" value="3">3 <br> <input class="ID_2" type="checkbox" value="4">4 <br> <input class="ID_2" type="checkbox" value="5">5 <br> </div> </body> </html>
