Onchange open URL via select - jQuery

问题:

What would be the best way to attach an event so on change of a select option a URL. Store the href in an attr and grab it on change?

回答1:

It is pretty simple, let's see a working example:

<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>

<script>
    $(function(){
      // bind change event to select
      $('#dynamic_select').on('change', function () {
          var url = $(this).val(); // get selected value
          if (url) { // require a URL
              window.location = url; // redirect
          }
          return false;
      });
    });
</script>

$(function() {
  // bind change event to select
  $('#dynamic_select').on('change', function() {
    var url = $(this).val(); // get selected value
    if (url) { // require a URL
      window.location = url; // redirect
    }
    return false;
  });
});

<select id="dynamic_select">
  <option value="" selected>Pick a Website</option>
  <option value="http://www.google.com">Google</option>
  <option value="http://www.youtube.com">YouTube</option>
  <option value="https://www.gurustop.net">GuruStop.NET</option>
</select>


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"
        ></script>

.

Remarks:

• The question specifies jQuery already. So, I'm keeping other alternatives out of this.
• In older versions of jQuery (< 1.7), you may want to replace on with bind.
• This is extracted from JavaScript tips in Meligy’s Web Developers Newsletter.

I think this is the simplest way:

<select onchange="if (this.value) window.location.href=this.value">
    <option value="">Pick one:</option>
    <option value="/foo">Foo</option>
    <option value="/bar">Bar</option>
</select>

Sorry, but there's to much coding going on here ...

I'll give the simplest one to you for free. I invented it back in 2005, although the javascript source now says it was their staff who came up with it - more than a year later!

Anyway, here it is, no javascript !!!

<!-- Paste this code into the BODY section of your HTML document  -->
<select size="1" name="jumpit" onchange="document.location.href=this.value"> 
<option selected value="">Make a Selection</option>
<option value="http://www.javascriptsource.com/">The JavaScript Source</option>
<option value="http://www.javascript.com">JavaScript.com</option>
<option value="http://www.webdeveloper.com/forum/forumdisplay.php?f=3">JavaScript Forums</option>
<option value="http://www.scriptsearch.com/">Script Search</option>
<option value="http://www.webreference.com/programming/javascript/diaries/">The JavaScript Diaries</option>
</select> 

Just type in any URL you like, or a relative URL (to the pages location on server), it will always work.

You can use this simple code snippet using jQuery to redirect from a drop down menu.

<select id="dynamic-select">
    <option value="" selected>Pick a Website</option>
    <option value="http://www.google.com/">Google</option>
    <option value="http://www.youtube.com/">YouTube</option>
    <option value="http://www.stackoverflow.com/">Stack Overflow</option>
</select>

<script>
    $('#dynamic-select').bind('change', function () { // bind change event to select
        var url = $(this).val(); // get selected value
        if (url != '') { // require a URL
            window.location = url; // redirect
        }
        return false;
    });
</script>

JS Fiddle Example

$('#userNav').change(function() {
window.location = $(':selected',this).attr('href')
});




<select id="userNav">
<option></option>
<option href="http://google.com">Goolge</option>
<option href="http://duckduckgo.com">Go Go duck</option>
</select>

This works for the href in an option that is selected

Here's how i'd do it

<select id="urlSelect" onchange="window.location = jQuery('#urlSelect option:selected').val();">
 <option value="http://www.yadayadayada.com">Great Site</option>
 <option value="http://www.stackoverflow.com">Better Site</option>
</select>

Another way:

    <script type="text/javascript">
        function change_url(val) {
            window.location=val;
        }
    </script>            
    <select style="width:130px;" onchange="change_url(this.value);">
            <option value="http://www.url1.com">Option 1</option>
            <option value="http://www.url2.com">Option 2</option>
     </select>

回答8:

If you don't want the url to put it on option's value, i'll give u example :

<select class="abc">
    <option value="0" href="hello">Hell</option>
    <option value="1" href="dello">Dell</option>
    <option value="2" href="cello">Cell</option>
</select>

    $("select").bind('change',function(){
        alert($(':selected',this).attr('href'));
    })

回答9:

<select name="xx" class="xxx" onchange="_name(this.options[this.selectedIndex].value,this.options[this.selectedIndex].getAttribute('rel'))">
  <option value="x" rel="xy">aa</option>
  <option value="xxx" rel="xyy">bb</option>
</select>


//for javascript
function _name(value,rel) {
alert(value+"-"+rel);
}

I believe the simplest way to redefine a location inside select tab is as follows:

<select onchange="location = this.value;">
     <option value="https://www.google.com/">Home</option>
     <option value="https://www.bing.com">Contact</option>
     <option value="mypets.php">Sitemap</option>
</select>

<script>
$(function() {

    $("#submit").hide();

        window.location = $("#page-changer select option:selected").val();
    })

});
</script>

<?php
    if (isset($_POST['nav'])) {
         header("Location: $_POST[nav]");
    }
?>
<form id="page-changer" action="" method="post">
