    Hi,

    Was just wondering if you can use javascript in the snippets? Here is the javascript i’m trying to get working, unless i have it wrong embarrassed

    <textarea id="reason" name="reason" onclick="javascript:document.this.value=\'\';">this text should be removed after the mouse clicks the textbox</textarea>


    I’m trying to get the textbox to clear when it’s clicked....

    Also, on the same subject, is there anyway to reference a pre-made javascript function from perhaps a seperate .js file that is included somewhere? or how does that work?

    Thanks.

      Hi Gaia,

      For the textarea, you are nearly there. You just need to remove the ’document.’ from the onclick event:

      <textarea id="reason" name="reason" onclick="javascript:this.value=\'\';">this text should be removed after the mouse clicks the textbox</textarea>


      For the external js, as long as you include a call to the external js file in the <head> part of your template, then you can use the functions contained within the file.

      You could use $modx->regClientStartupScript to place the necessary code automatically in the head on any page the snippet is used - but you will need to apply a fix (run a search in this forum and you’ll find the details) to make this work.

      Hope that helps, Garry
