javascript - Unable to get the RegisterClientScriptBlock() method to work when passing "true" as last Boolean parameter -


here 3 versions tried include scripts in page: 

page.clientscript.registerclientscriptblock(this.gettype(), "jquerytestfile1",      "<script type=\"text/javascript\" src=\"jquerytest1.js\"></script>", false);  page.clientscript.registerclientscriptinclude(this.gettype(), "jquerytestfile2",      "jquery-1.11.0.min.js");  page.clientscript.registerclientscriptblock(this.gettype(), "jquerytestfile3",      "src=\"jquerytest3.js\"", true);

the first 2 versions working fine . 3rd 1 "true" last parameter rendering <![cdata[ in source code , can't work.

why rendering cdata ? purpose serves in context? how can third version working without removing "true" parameter ? below html code rendered in browser::

<form method="post" action="scriptsmanager.aspx" id="form1">      <script type="text/javascript" src="jquerytest1.js"></script>      <script src="jquery-1.11.0.min.js" type="text/javascript"></script>      <script type="text/javascript">           //<![cdata[           src="jquerytest3.js"//]]>      </script>      <input type="button" value="clickme" onclick="doclick()" />      </form>

additional info::

[ avoiding confusion these js files: jquerytest1.js etc.. present @ proper location in solution ]. in jquerytest3.js, have below code: 

function doclick(){ alert("hi"); }

if place doclick() function in jquerytest1.js file, works perfectly.

.aspx markup:

<form id="form1" runat="server">   <input type="button" value="clickme" onclick="doclick()" />  </form>

replace code following

    scriptmanager.registerstartupscript(this,this.gettype(), "jquerytestfile3",  "src=\"jquerytest3.js\"", true)

remember add page
