Run any other javascript after the Display Templates have rendered the content

Question

This is the issue:

1. I create a ContentBySearchWebpart, specified with my custom Display templates.'
2. I want to run some other javascript code, after the Display Templates have rendered the content

3. I then register my custom javascript file in Display template.

           $includeScript(this.url, "~sitecollection/_catalogs/masterpage/Display Templates/Slider.js")'
   

   The problem is that my Slider.js file code executes before the 'Display Templates' Javascript code does.

Can anybody provide me a way to execute my Slider.js code after the display templates have rendered the content of ContentBySearchWebpart(CSWP)?

Answer 1

:) my issue is solved.

I did following:

1. Registered the custom JS file in Control_YourTemplateName.html file(like Control_Banner).

   $includeScript(this.url, "~sitecollection/_catalogs/masterpage/Display Templates/HWScripts/Banner.js");

2. Added these three lines under the first div after body tag, in YourTemplateName.html (like Banner.html) file.

    <!--#_  
    ctx.OnPostRender = [];
    ctx.OnPostRender.push(function(){ 
       CustomMethodWhichIsIncludedInTheCustomJSFile();
    });
    _#-->  
   

But a better solution is provided below:

You can skip defining OnPostRender yourself. CBS Display Templates have this function baked in:

<!--#_
   AddPostRenderCallback(ctx, function(){
       alert(ctx.Title + "finished rendering!");
   });
_#-->

There is also AddPreRenderCallback(ctx, function(){});

You can add line of code after including script,

ExecuteOrDelayUntilScriptLoaded( function() { <your custom function name>; }, 'name of   display template ');

for example:

ExecuteOrDelayUntilScriptLoaded( function() { console.dir( SP.Res ); }, 'sp.js');
