[B]Basic conditional logic
Using the tpl tag and the if operator you can provide conditional checks for deciding whether or not to render specific parts of the template. Note that there is no else operator — if needed, you should use two opposite if statements. Use of multiple conditions is supported via the && and || operators. Properly-encoded attributes are required as seen in the following example:

It would be more correct to say that the if condition can be any javascript expression (including all operators).
Sidenote: the " character needs to be written as " to avoid conflicts with detecting the end of the expression.

Sidenote: the " character needs to be written as " to avoid conflicts with detecting the end of the expression.

I missed your point here. Can you post sample text for the docs to demonstrate?

[Condor]

The current XTemplate doc already contains an encoded example:

<tpl if="age &gt; 1">',  // <-- Note that the > is encoded

But the only character that should actually be encoded is the double quote: " (")

Encoding & (&amp;), < (&lt;) or > (&gt;) is optional.

Got it... By all operators this means we can use arithmetic operators right?.

I like your version (the if condition can be any javascript expression (including all operators))

I would just perhaps change the example to make the above statement a little bit more obvious, i.e. :

     '<tpl if="age + 1 &gt; 1 && name='Zachary'">',  // <-- Note that the > is encoded 

The current XTemplate doc already contains an encoded example:

<tpl if="age &gt; 1">',  // <-- Note that the > is encoded

But the only character that should actually be encoded is the double quote: " (&quot

Encoding & (&amp, < (&lt or > (&gt is optional.

AHA! So that's why I didn't have to encode the &&, good to know..

[mjlecomte]

Ok, here's an update, voice any concerns. Note that both ways are shown. Encoding the operator is shown in the example above the conditional section (image 1). Encoding the closing double quote along with && is shown in the example of second image, along with revised text.

[mjlecomte]

I patched up the 2nd image from the last comment.

[Condor]

I think you missed the point on the &quot; encoding.

You need to encode " if it is part of the condition, e.g.

<tpl if="name == &quot;Jack&quot;">Hello</tpl>

Yes, I miss the point still. Your prior post has confused me. I haven't changed the docs.

Would it be appropriate to say the only character that has to be encoded is double quote (or whatever the opening symbol for the "if" string is:

<tpl if="name == ...<encode any double quotes here>... ">Hello</tpl> // must encode any double quotes inside if expression

<tpl if='name == ...<encode any single quotes here>... '>Hello</tpl> // must encode any single quotes inside if expression

[Condor]

OK, the following examples are valid:

<tpl if="age &gt; 1 &amp;&amp; age &lt; 10">Child</tpl>
<tpl if="age >= 10 && age < 18">Teenager</tpl>
<tpl if="name == &quot;Jack&quot;">Hello</tpl>

and this one isn't:

<tpl if="name == "Jack"">Hello</tpl>

[aurelien]

in the createDelegate method into the Function class it seems that :

...Example: this.myFunction.createDelegate(this, [arg1, arg2])...

should be replaced by

...Example: this.myFunction.createDelegate(obj, [arg1, arg2])...
