该模版在条件{{{1}}}下调用模版{{{2}}}并使用参数{{{3}}}，且在结尾添加一个换行符。

该模板用于避免两次写出条件：一次用于模板调用，一次用于换行。[[Template:If]]可用于保留换行符。

==用法==
===Sample 1===
Example using [[Template:2x]], which simply repeats its argument twice, so <code><nowiki>{{2x|Pizza}}</nowiki></code> produces {{2x|Pizza}}. One can combine this with {{tld|Conditional template call with newline}} in the following code

<code><nowiki>{{#tag:pre|{{Conditional template call with newline|1|2x|Pizza}}{{Conditional template call with newline|0|2x|Bora}}{{Conditional template call with newline|1|2x|Bang}}}}</nowiki></code>

:which produces

{{#tag:pre|{{Conditional template call with newline|1|2x|Pizza}}{{Conditional template call with newline|0|2x|Bora}}{{Conditional template call with newline|1|2x|Bang}}}}

Notice how {{2x|Bora}} is suppressed, and there is a newline between {{2x|Pizza}} and {{2x|Bang}}.

===Sample 2===
Example using {{tl|Table row Dutch municipality}}

<pre style="overflow:auto">
{| class="wikitable sortable"
!Municipality!!Population
{{Conditional template call with newline|1|Table row Dutch municipality|Delft}}{{Conditional template call with newline|0|Table row Dutch municipality|Hoorn}}{{Conditional template call with newline|1|Table row Dutch municipality|Rotterdam}}|}
</pre>

gives

{| class="wikitable sortable"
!Municipality!!Population
{{Conditional template call with newline|1|Table row Dutch municipality|Delft}}{{Conditional template call with newline|0|Table row Dutch municipality|Hoorn}}{{Conditional template call with newline|1|Table row Dutch municipality|Rotterdam}}|}

The template is typically called by another table row template, which has as parameter {{{1}}} the identification of the potential item (in this template: {{{3}}}), and some parameter {{{2}}} related to the condition. That template provides the condition in terms of {{{1}}} and {{{2}}}.

===Sample 3===
Sample usage with full substitution of the template to create a newline in wikitext.

1. Create a sample template : "[[Template:testnewline]]"
<pre style="overflow:auto">
ABC{{<includeonly>subst:</includeonly>Conditional template call with newline|{{<includeonly>subst:</includeonly>#ifeq:{{{align|}}}|{{{align}}}|1|0}}|void|1|substctc=subst:|subst=subst:}}
DEF
</pre>

2. When called empty (<nowiki>{{subst:testnewline}}</nowiki>), it generates the following wikitext:
<pre>
ABC
DEF
</pre>

3. When called as <nowiki>{{subst:testnewline|align=somevalue}}</nowiki>, it generates the following wikitext (note the newline):
<pre>
ABC

DEF
</pre>

==参数==
===必选参数===
;<tt>1</tt>: 第一个未命名参数，用于判断条件。其中1代表真（True），而0代表假（False）。如果条件为真，那么第二个模板将被调用，并在结尾添加一个换行符。可直接输入0或1。<br />示例：<nowiki>{{#ifeq:{{{align|}}}|{{{align}}}|1|0}}</nowiki>。当一个模板被调用，且使用align为任意值的参数时条件为真：而align未包含时条件为假。
;<tt>2</tt>: 第二个未命名参数，为需要调用模板的名称。<br />可使用[[Template:!]]代替“!”，[[Template:Void]]代替“void”。

===可选参数===
;<tt>3</tt>: 3rd unnamed parameter, value to be assigned to {{{1}}} when calling template {{{2}}}
;<tt>substctc</tt>: for substitution of some parser functions and auxiliary templates called inside the template, use the value "subst:"; recommended when the template is substituted; note that in that case any parser functions or templates in the condition have to be substituted too.
;<tt>subst</tt>: for substitution of template {{{2}}}, use the value "subst:"
;<tt>p1n</tt>: name of an additional parameter used by template {{{2}}}
;<tt>p1v</tt>: value to be assigned to {{{p1n}}} when calling template {{{2}}}
