p.render(data, directives);
$(".result").after(p);
});
</script>

The above codes don't insert data into p object.But the following works,
<html lang="en">
<head>
<meta charset="utf-8">
<script type='text/javascript' src="js/jquery/jquery-min.js"></script>

<script type='text/javascript'>
$(document).ready(function(){
var p;
p = $("<div><ul><li></li></ul></div>");
$(".result").after(p);
directives = {"li": "error"};
data = {"error": "name must be between 3 and 250 characters long"};
p.render(data, directives);
});
</script>
</body>
</html>
It seems to insert data, the jquery object(here,it is p)must manipulate the existing html tags? It is not reasonable like the latter,i want the first codes to insert data,but how?
Thanks, :)
render returns always a node. And if the template is in the DOM, it is replaced with the rendered node.
You can do this:
p = p.render(data, directives);
$(".result").after(p);
or
$(".result").after( p.render(data, directives) );

So, I'm trying to render a template from an external file, and when I render it, it "works," just that it sends the script, not the actual script contents to the target.
I tried using the jquery .html() function to grab the inside contents of the script, but all I get is "undefined"
This is the body content:
<div id="target"></div>
<script>
var context = {"name": "Test"};
$.get('template.handlebars', function (data) {
var templateScript = Handlebars.compile(data);
var html = templateScript(context);
$(document.body).append(html);
}, 'html')
</script>
What I get is this:
<div id="target"></div>
<script>blah blah blah</script>
<script type="text/x-handlebars-template" id="template">
<h1>Test</h1>
</script>
Instead of
<div id="target">
<h1>Test</h1>
</div>
In response to someone's question:
Doing "body" instead of document.body has the same effect. The contents of the template document are:
<script type="text/x-handlebars-template" id="template">
<h1>{{ name }}</h1>
</script>
In your scenario, you have the handlebars template in a separate file –– which is not a HTML file, so you should try removing the script tag. According to the handlebars docs, they want you to include the script tags for shielding from HTML parser, but in your case that should not be a problem.
Next your jQuery $(document.body).append(html); is selecting the document body and appending the resulting HTML snippet.
To achieve the:
<div id="target">
<h1>Test</h1>
</div>
you'll have to select the target div. Doing a $("#target").html(html); should solve that issue.
I've created a sample to simulate your scenario, hope this gives more insight.

I'm creating a website for a school project with different arrays of facts. I created multiple files with different JavaScript facts arrays and am trying to call them in the index.html file but I'm not sure how to call them without an a href tag. I've researched and most people say to try sourcing in the tag but nothing is printing.
This is my index.html code:
<!doctype html>
<html>
<head>
<meta charset="utf8" />
<title></title>
<link rel="stylesheet" type="text/css" href="main.css" />
<script src="EllaFactsArray.html" type="text/javascript"></script>
</head>
<body>
<p>
Here is a fact about Ella:
</p>
<script>
getEllaFact();
</script>
</body>
</html>
This is my facts array (EllaFactsArray.html):
<html>
<title>Ella Facts</title>
<head>
<script type="text/javascript">
function getEllaFact()
{
Ella = new Array(6);
Ella[0] = "Ella had a six decade long career.";
Ella[1] = "";
Ella[2] = "";
Ella[3] = "";
Ella[4] = "";
Ella[5] = "";
i = Math.floor(Math.random() * Ella.length);
document.write("<dt>" + Ella[i] + "\n");
}
</script>
</head>
<body>
<script type="text/javascript">
getEllaFact();
</script>
</body>
</html>
The script needs to reference a JavaScript file, not an HTML file containing a function. Move the function into its own file and include it in the pages as needed.
<script src="EllaFactsArray.js" type="text/javascript"></script>

I tried to create two buttons, so that when I click on each- I will get a pop up small window, with a content that it will get while onloading.
This is the code:
index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="script.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body ng-app="myApp">
<p ng-controller="ctrl">
<span ng-repeat="x in items">
<button ng-click="parentFunc(x.fieldOne,x.fieldTwo)">{{x.fieldOne}}</button>
<br><br>
</span>
</p>
<script>items();</script>
</body>
</html>
script.js:
var title, content;
function items(){
angular.module('myApp', []).controller('ctrl', function($scope) {
$scope.items = [
{fieldOne:"field1", fieldTwo:"field1 content"},
{fieldOne:"field2", fieldTwo:"field2 content"}
];
$scope.parentFunc=function(titleTmp,contentTmp){
title=titleTmp;
content=contentTmp;
var OpenWindow = window.open('popUp.html','_blank','width=500, height=400');
return false;
}
});
}
function codeAddress() {
document.getElementById("title").innerHTML=title;
document.getElementById("content").innerHTML=content;
}
popUp.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="script.js"></script>
</head>
<body onload="codeAddress();">
<h1 id="title"></h1>
<div id="content"></div>
</body>
</html>
The new pop up window open as expected, but the h1 and div in it get undefined. I tried to debug it, and I saw that after the first two lines of parentFunc are executed, the global variables title and content get what I expect and they are not undefined. However, when the third line is executed and the new window get opened- the global variables are undefined.
Why the two global variables are undefined in the pop up window?
And how can I solve this?
Your method won't work : you are trying to reload the script.jsand then, the vars are reinitialized.
Add your vars in the URL :
var OpenWindow = window.open('popUp.html?title='+titleTmp+'&content='+contentTmp,'_blank','width=500, height=400');
Then, in your second page, read those parameters :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript">
function codeAddress(){
var title = GET_TITLE_FROM_PARAMETER;
var content = GET_CONTENT_FROM_PARAMETER;
document.getElementById("title").innerHTML=title;
document.getElementById("content").innerHTML=content;
}
</script>
</head>
<body onload="codeAddress();">
<h1 id="title"></h1>
<div id="content"></div>
</body>
</html>
And of course, remove codeAddress from the first page as it's useless.
FYI, to get the parameters values, please check this answer.
#(message: String)(exchangelist: java.util.ArrayList[String])(implicit session: play.mvc.Http.Session)
#main(title = message)(session) {
<head>
...
</head>
<body>
<script>
startup(exchangelist);
<script>
</body>
Code like this, how can I pass parameter "exchangelist" to Js function "startup()"? This method don't work.
I suggest trying the meta tag:
<html>
<head>
<!-- <meta name="exchangelist" content='#{exchangelist.mkstring(",")}'> -->
<meta name="exchangelist" content='yellow,black,green'>
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
</head>
<script>
function startup(list) {
alert("startup called with " + list);
}
var el = $('meta[name=exchangelist]').attr("content").split(",");
startup(el);
</script>
</html>
If I have some hidden element on a page, that contains some content, how can I create a link and when user clicks it, browser would open a new window and show the content (only the content, for example some json data)?
ps. I know that's probably bad idea to have some hidden content on the page. It's better to put an action link that will get the content from the server.. But it involves many other headaches and it wasn't me who created the page, so please just let me know if there's a comparatively easy solution...
Please use http://okonet.ru/projects/modalbox/index.html with inline content setting
You could pass the (URL encoded) contents of the hidden element as an argument in the URL when opening the second page. That argument could then be (unencoded and) inserted into the body of the second page when it loads.
The following example works locally on OS X. On other operating systems, the example may need to be placed on an actual web server before it will work:
page1.html:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script>
function openwindow(){
window.open("page2.html?html="+escape($("#myDiv").html()));
