eWriter -- anchor to top

[John Johann]

I created some anchors in a topic to avoid having to scroll.
At a certain point in the topic, I have 3 topic links to the same topic with the name of the anchor.
Beside each of the three jump targets, I created a topic link to the same topic with the default (Top).

When I publish to eWriter, I can jump down to the anchors but not back to the top.
When I publish to CHM, I can jump up and down

Do I need to define a custom anchor for the top of the page for eWriter?

Hi John,

You're using a V3 or V4 skin, where this won't work quite the same because of the way topics are referenced. However, you can easily create a scroll to top link, it's just a little different. Instead of creating a regular topic link, create a script link and enter this code in the Script: box:

Code: Select all

javascript:hmpage.$scrollBox.scrollTo(0, 600)

The first value is the vertical position, the second is the number of milliseconds that the scroll operation should take.

Hi Tim,
I copy/pasted the code but receive a blank page with [object Object] when I build and click on the link.

I then replaced "hmpage" with the name of the topic page (without extension) -- nothing happens when I build and click on the link.

I'm using the Minimalist blue eWriter skin (modified some colours and CI).

Hi John,

You're probably using the wrong link type, otherwise you won't see the Object display. See here:

Hi Tim,
That's exactly how I have set it -- no joy.
I've now just inserted a normal anchor at the top of the page and link to it. That works fine so it's not really an issue as long as I don't forget .

Oops, thanks for reporting this. I only did a quick check in WebHelp, since it's the same code. It's a problem with script links with some kinds of content in eWriter. The Windows WebView component apparently doesn't like script links with a certain kind of characters in them. Here's how to solve this:

Edit the hm_webhelp.js file in the skin and locate this line of code:

Code: Select all

jQuery.cachedScript = function( url, options ) {

Then add this code directly ABOVE it:

Code: Select all

  // Scroll to top for script link use
   var ScrollTop = function() {
	   hmpage.$scrollBox.scrollTo(0,600);
   }

Then for your script links to scroll to the top use:

Code: Select all

javascript:ScrollTop();

I'm going to add the ScrollTop function to the scripts in the next update, so you will be able to go on using it without any changes.
