Why is this jQuery click function not working?

2019-01-03 02:12发布

Code:

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $("#clicker").click(function () {
        alert("Hello!");
        $(".hide_div").hide();
    });
</script>

The above code doesn't work. When I click on #clicker, it doesn't alert and and it doesn't hide. I checked the console and I get no errors. I also checked to see if JQuery was loading and indeed it is. So not sure what the issue is. I also did a document ready function with an alert and that worked so not sure what I am doing wrong. Please help. Thanks!

You are supposed to add the javascript code in a $(document).ready(function() {}); block.

i.e.

$(document).ready(function() {
  $("#clicker").click(function () {
    alert("Hello!");
    $(".hide_div").hide();
  });
});

As jQuery documentation states: "A page can't be manipulated safely until the document is "ready." jQuery detects this state of readiness for you. Code included inside $( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute"

Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.
