javascript 函数在 php echo 中不起作用

Question

大家好，你能帮我吗？我想回显我的按钮，但似乎我的 JS onclick 功能无法工作

 echo "<th><button id="btnPrint" type="button" class="btn btn-primary " onclick="pindah('<?php echo $row->id ; ?>')">Detail Laptop &nbsp;<span class="fa fa-info"></span></button></th>"; 

Answer 1

(As stated by others already) You need to use the correct quotes. And concatenate your value instead of using <?php echo... when you already use echo to output:

echo '<th><button id="btnPrint" type="button" class="btn btn-primary" onclick="pindah(' . $row->id . ')">Detail Laptop &nbsp;<span class="fa fa-info"></span></button></th>';

Answer 2

You need to escape the double quotes as the php statement is not completely error-free. Also please have a look at the below link for more details.

Link: echo and print in PHP

 echo "<th><button id=\"btnPrint\" type=\"button\" class=\"btn btn-primary \" onclick=\"pindah('<?php echo $row->id ; ?>')\">Detail Laptop &nbsp;<span class=\"fa fa-info\"></span></button></th>";

Answer 3

It will not work. JS is a client side scripting language. we cannot execute php code in javascript. please change your code in such a way it will do a post back on click or will make AJAX request on click.
