Jquery Don't Work

Yii 2.0 General Discussions

Hello, I tried to write a lot of jQuery in my project and didn’t work, I already tried to create a clean and updated project and the simplest jQuery doesn’t work. Here is one example:




   <select name="dropdown" size=1>

    <option value="1">option 1</option>

    <option value="2">option 2</option>

</select>

    

    <?php

    use yii\web\View;

  $this->registerJs('

 $("select[name="dropdown"]").change(function(){

  

    if ($(this).val() == "2")

        alert("call the do something function on option 2");

    

});', View::POS_END);

  ?>

But the function is in the end of the file like it’s suposed I think




</script><script src="/basic2/web/assets/749ae052/jquery.js"></script>

<script src="/basic2/web/assets/d2986435/yii.js"></script>

<script src="/basic2/web/assets/3b96795f/js/bootstrap.js"></script>

<script type="text/javascript">

 $("select[name="dropdown"]").change(function(){

  

    if ($(this).val() == "2")

        alert("call the do something function on option 2");

    

});</script></body>

</html>

Please help.

Pretty sure your problem is with the quotes here:


$("select[name="dropdown"]")

Try this:


$("select[name='dropdown']")

Thanks a lot for the reply. I got it work on this way:


<?php

    use yii\web\View;

  $this->registerJs("

 $('select[name="."dropdown"."]').change(function(){

  $("."'#teste'".").html('call the do something function on option '+$(this).val());

    if ($(this).val() == '2')

        alert('call the do something function on option 2');

    

});", View::POS_READY);

  ?>
