Js drop down working on one page but not another? WordPress

Dbranes answers:

You have to add

<div class="oline">
<canvas id="mycanvas"></canvas>
</div>


to this page, otherwise you get a javascript error.

On the <strong>/portfolio/</strong> page, where it is working you have:

<div class="title container">
<div class="row">
<div class="twelvecol">
<h1 class='text'>Portfolio</h1>

<div class="oline">
<canvas id="mycanvas"></canvas>
</div>
</div>
</div>
</div>

The problem is in the <em>common.js</em> file just as @Arnav mentioned above, there you have

var canvas = document.getElementById('mycanvas');


and when there is no #mycanvas you get a javascript error when you later try to call

if (canvas.getContext) {

<strong>EDIT:</strong>

You could also modify <em>common.js</em> by replacing

if (canvas.getContext) {


with:

if ( typeof(canvas.getContext) !== 'undefined' && canvas.getContext) {


cheers

In order to set up a drop-down menu to redirect to a new Web page, you need to add some simple JavaScript to your form.

First you need to set up your <option> tags to include the URL as the value - so that your form knows where to send the customer:

<option value="/">Web Design Front Page</option>
<option value="/library/beginning/bl_begin.htm">Beginning HTML</option>

Then you need to add an "onchange" attribute to your <select> tag to tell the browser what to do when the option list changes (put the JavaScript all on one line):

<select name="URL" onchange="window.location.href= this.form.URL.options[this.form.URL.selectedIndex].value">

Make sure that your select tag is named "URL" - if it isn't, change the JavaScript above where ever it says "URL" to read your select tag's name.
