[TW5]Can I use a field's value as a color code in template?

[Terry Chen]

I created a tiddler "list" like this:

<$list filter='[tag[role]]' template='role_color_template'></$list>

and another tiddler named "role_color_template" like this:

<$view field='colorcode'/><br/>

this is the correct way to create a template, right?

Then I created a tiddler name "customer" with tag "role". I gave a field name="colorcode", value="#FF0000" to it.

So, in the "list" tiddler, it shows:

#FF0000

But, when I tried to put the code in "font" tag, just like this:

<font color="<$view field='colorcode'/>">The quick fox...</font><br/>

it doesn't work.

Is that possible?

You can't use a widget as the input to an attribute. Widgets are like HTML tags. Just as you can't have an HTML tag inside (used as an attribute) another HTML tag, you can't use a widget inside an HTML tag.

But you can use transclusion, due to the miracle of wikitext rendering. So if you change your template to:

<font color={{!!colorcode}}>The quick fox...</font><br/>

This will work.

Good luck

@Terry Chen, you can do this, also using the <$view..> widget, but Mark's solution is easier.

Using the <$wikify> widget:

<$wikify name="colorcode" text="<$view field='colorcode'/><br/>">
<font color=<<colorcode>>>The quick fox...</font><br/>
</$wikify>

May I ask a further question?

when I use a "span" tag, it doesn't work again:

<span style=color:{{!!colorcode}}>abc</span><br/>

Can I use it this way?

Use the method by BurningTreeC!

It should work!

<$wikify name="colorcode" text="color:{{!!colorcode}}">

<span style=<<colorcode>>>abc</span><br/>

</$wikify>
