Complex Tag
A tag composed of multiple tags.
Layout
${ layout(path)} or $layout(path) - like ASP.NET Web Forms Masterpage.
example (parent.html):
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JNTemplate demo</title>
</head>
<body>
${body}
</body>
</html>
example(child.html):
$layout("parent.html")
<p>i'm child!</p>
output:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JNTemplate demo</title>
</head>
<body>
<p>i'm child!</p>
</body>
</html>
WARNING
Applies to v1.4.0+
IF
If statement in jntemplate is used to evaluate a set of statements conditionally based on an expression that evaluates to true or false.
example
var templateContent = @"
$if(value>5)
value is greater than 5.
$elif(value<5)
value less than 5.
$else
value equals 5.
$end
";
var template = Engine.CreateTemplate(templateContent);
template.Set("value", 10);
var result = template.Render();
Assert.AreEqual("value is greater than 5.", result);
Foreach
Iteration is achieved by using the foreach binding on the element you wish to iterate.
$foreach(child in list)，
...
$end
or
$for(child in list)，
...
$end
The list must implement the IEnumerable interface. And ends with $end.
example
var templateContent = @"
<ul>
$foreach(i in list)
<li>$i</li>
${end}
</ul>
";
var template = Engine.CreateTemplate(templateContent);
template.Set("list", new char[] { 'j', 'n', 't', 'e', 'm', 'p', 'l', 'a', 't', 'e' });
var result = template.Render();
output:
<ul>
<li>j</li>
<li>n</li>
<li>t</li>
<li>e</li>
<li>m</li>
<li>p</li>
<li>l</li>
<li>a</li>
<li>t</li>
<li>e</li>
</ul>
TIP
The list must implement the IEnumerable interface.
For
The for statement executes a statement or a block of statements while a specified Boolean expression evaluates to true.
$for(initializer; condition; iterator)
...
$end
example
var templateContent = @"
<ul>
$for(i=1;i<4;i++)
<li>$i</li>
${end}
</ul>
";
var template = Engine.CreateTemplate(templateContent);
var result = template.Render();
output
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
Set
$(set key=value) - Used to define a variable or change the value of a specified variable.
example
var templateContent = "$set(id=10)$id";
var template = Engine.CreateTemplate(templateContent);
var result = template.Render();
Assert.AreEqual("10", render);
WARNING
You can only assign values to variables, not attributes or fields.
Load
$load(path) - The tag is used to load the specified template and parse the template content.
example：header.html：
<p>hello,$name</p>
code
var templateContent = "$load(\"header.html\")";
var template = Engine.CreateTemplate(templateContent);
template.Set("name","jntemplate");
var result = template.Render();
output:
<p>hello,jntemplate</p>
Include
$include(path) - The tag is used to load the specified template, but does not parse the template content.
example：header.html：
<p>hello,$name</p>
code
var templateContent = "$load(\"include.html\")";
var template = Engine.CreateTemplate(templateContent);
template.Set("name","jntemplate");
var result = template.Render();
output:
<p>hello,$name</p>
