当我的代码添加到wordpress中时，为什么按键事件不起作用？

Question

The following code works flawlessly here, but on WP not so much. When I inspect the console there are no errors.

$('input[name="tmp_post_tag"]').keypress(function(event) {

    var keycode = (event.keyCode ? event.keyCode : event.which);   
    if (keycode == '13'){ 
        event.preventDefault();
        alert('You pressed a "enter" key in textbox');
    }    
});  

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="">
    <input type="text" 
            id="cant_use" 
            name="tmp_post_tag" 
            value="" 
            data-taxonomy="post_tag" 
            data-taxtype="flat" 
            class="wpt-new-taxonomy-title js-wpt-new-taxonomy-title form-control wpt-form-textfield form-textfield textfield"
            data-wpt-type="textfield" 
            data-wpt-id="cant_use" 
            data-wpt- autocomplete="off">

</form>

What am I doing wrong? FYI we are using input name because ID changes. Dont think thats the issue because it wirks here,

Answer 1

可能是内容是动态生成的，请尝试在其中使用on函数和keypress事件。

$('input[name="tmp_post_tag"]').on('keypress',function(event) 

Answer 2

WordPress自己的jQuery接管了$变量，因此您需要改用jQuery ，即： jQuery('input[name="tmp_post_tag"]').keypress(function(event) {
