Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Need to press the button twice

    This code works in an Html page and an a5w page as expected.


    jQuery('button').click(function()
    {
    var url='data:application/vnd.ms-excel,' + encodeURIComponent(jQuery('#tableWrap').html())
    location.href=url
    return false
    })

    However in a dialog component it requires 2 clicks to work.

    Anyone got any idea why this is so?

      Re: Need to press the button twice

      The program works, but after the second click on an on click event.

      The first click does nothing.
      ---------------------------------------------------------------------------------------
      HTML page in <Head>
      <script type="text/javascript">
      $(function(){
      $('button').click(function(){
      var url='data:application/vnd.ms-excel,' + encodeURIComponent($('#tableWrap').html())
      location.href=url
      return false
      })
      })
      </script>

      <body>
      <button>click me</button>
      <div id="tableWrap">
      <table>
      <thead>
      <tr><th>Qty</th><th>Qty Available</th><th>Grower</th></tr>
      </thead>
      <tbody>
      <tr><td>1</td><td>2</td><td>Frog</td></tr>
      <tr><td>21</td><td>22</td><td>Cat</td></tr>
      <tr><td>31</td><td>32</td><td>Dog</td></tr>
      <tr><td>41</td><td>42</td><td>Fish</td></tr>
      </tbody>
      </table>
      </div>
      </body>

      This works on the first click.
      ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

      Dialog

      function mark(){

      var qty = {dialog.Object}.listGetValue('ListDemo','Bottle');
      var name = {dialog.Object}.listGetValue('ListDemo','WineName');
      var year = {dialog.Object}.listGetValue('ListDemo','Year');

      var save = localStorage.getItem('lsrow');

      if(save == undefined ){

      //Build the header

      var txt = "<table><thead><tr><th>Qty</th><th>Wine</th><th>Year</th></tr></thead><tbody>"


      }
      else


      var txt = localStorage.getItem('lsrow');

      alert(txt);
      var row = "<tr><td>" + qty + "</td><td>" + name + "</td><td>" + year + "</td></tr>"
      txt = txt + row
      // End
      localStorage.setItem('lsrow',txt);

      {dialog.object}.runAction('table');




      }

      This function builds the table in a new panel. Mark() is called from the on click event of a list row.

      Then I have a button on the new panel

      jQuery('button').click(function()
      {
      var url='data:application/vnd.ms-excel,' + encodeURIComponent(jQuery('#tableWrap').html())
      location.href=url
      return false
      })

      Works in the correct way on second and subsequent click.

        Did you define your jQuery('button').click(...) in one of the events for the new button? Or is it defined in the JavaScript code section for the UX?

          Sorry I have had to move on. It was on the button's onclick event.

          PS if I manage a solution that works I will share it. (I have a good solution for Chrome Firefox but it does not work in IE)

            Hi Michael,

            If your jQuery code is defined in the button's click event---the click event for the button that is supposed to perform this action ---then it makes sense that it doesn't work the first time. The first time you click the button, the jQuery code you have there executes and a function is registered for the 'click' event for all 'button' elements. The second time you click the button, the function you bound to your button's click event is executed *and* your jQuery code executes again - possible registering your function on the click event twice, which potentially means it's called twice the third time you click the button (if clicking the button a third time is possible.)

            The way I see it, you have 2 options:

            Option 1: Move the entire block of code to the client-side "onInitializeComplete". You want to register the event handler once - ideally immediately after the button has been rendered/added to the DOM. If the button is dynamically added later (ie, not during the first load of the UX), then you need to look to another location to put your jQuery code so that you can execute it after the HTML is added to the DOM.

            Option 2: If you're already putting this code inside the button's click event, then instead of registering the event handler, you could just execute the code directly:
            Code:
            var url='data:application/vnd.ms-excel,' + encodeURIComponent(jQuery('#tableWrap').html());
            location.href=url;
            return false;
            Good luck
            ---
