Here's the scene:
The webpage doesn't have a google+ button.
User clicks a button.
AJAX request is sent which loads some text and the google+ button (<g:plusone href="http://www.website.com"></g:plusone>)
into a div.
I can see when I look at the code that it is there, but it is not rendering.
I've heard that this might be useful:
gapi.plusone.go();
But I'm not sure.
Any ideas?
Thanks
You're on the right track. gapi.plusone.go() is one way to explicitly render the +1 button. Here's a code snippet from the official docs that illustrates another method using gapi.plusone.render().
<html>
<head>
<title>+1 Demo: Explicit render</title>
<link rel="canonical" href="http://www.example.com" />
<script type="text/javascript" src="https://apis.google.com/js/plusone.js">
{"parsetags": "explicit"}
</script>
<script type="text/javascript">
function renderPlusone() {
gapi.plusone.render("plusone-div");
}
</script>
</head>
<body>
Render the +1 button
<div id="plusone-div"></div>
</body>
</html>
The JavaScript API is further documented elsewhere on the previously linked page.

I am doing my damnedest to embed a Google trends chart into a section of my site.
In theory, it seems easy:
1.) copy script from Google:
2.) Clear a space in your webpage:
3.) Add the code:
<div class="full-row4" style="height: 300px;">
<script type="text/javascript" src="https://ssl.gstatic.com/trends_nrtr/1386_RC02/embed_loader.js"></script>
<script type="text/javascript">
trends.embed.renderExploreWidget("TIMESERIES", {"comparisonItem":[{"keyword":"/m/078rys","geo":"","time":"today 12-m"}],"category":0,"property":""},
{"exploreQuery":"q=%2Fm%2F078rys&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"}
);
</script>
</div>
Seems easy right? wrong!
Every time I do this, I get this result:
Upon further inspection, I found that when those scripts were loaded in, it wipes my entire body of the webpage. (Note: the chart gets loaded in thru an AJAX call containing the entire active page minus the navbars)
I've tried an array of different logic to try and get this to work, but everything I try deletes all HTML in the body tag of the webpage. (script tags are still there)
I found people with a similar issue, but it seems Google has changed how you embed these widgets into a site. Rendering any previous stackoverflow documentation useless. (at least from what I found)
you can use renderExploreWidgetTo() function instead, it takes DOM element as first parameter:
var divElem = document.getElementById('wrapper');
trends.embed.renderExploreWidgetTo(divElem,"TIMESERIES", {"comparisonItem":[{"keyword":"dbs bank","geo":"","time":"today 12-m"}],"category":0,"property":""}, {"exploreQuery":"q=dbs%20bank&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"});
Google trends embed script create an iframe at the hosting website.
Here is a simple example.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JS Bin</title>
</head>
<body>
<h1>hello</h1>
<div>
<script type="text/javascript" src="https://ssl.gstatic.com/trends_nrtr/1386_RC02/embed_loader.js"></script> <script type="text/javascript"> trends.embed.renderExploreWidget("TIMESERIES", {"comparisonItem":[{"keyword":"dogs","geo":"","time":"today 12-m"}],"category":0,"property":""}, {"exploreQuery":"q=dogs&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"}); </script>
</div>
<h1>world</h1>
</body>
</html>
As you can see, the body is not affected.
The problem is probably not with the trends scripts, but a more general issue.
Try creating an iframe at your page, does it display correctly?
In Javascript, I want to open my window.html file in a popup window. But it doesn't display any text. Just a blank page.
This is index.html:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
<script language="javascript">
var newwindow;
function popit(url){
newwindow = window.open(
url, '', "status=yes, height=500; width=500; resizeable=0");
}
</script>
</head>
<body>
CLICK ME!
</body>
</html>
window.html:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>SAMPLE TEXT</p>
</body>
</html>
Why doesn't it display any text?
javascript:popit(window.html);
Replace with:
javascript:popit('window.html');
Your click handler code is syntactically incorrect:
CLICK ME!
Always, always have your developer console open to check for JavaScript errors! (edit — actually in this case there wouldn't have been an error; window.html would resolve to undefined probably! Still, keep the console open :-)
Also note that I used an "onclick" attribute instead of "href".
A GOOD working code with NO crashes.
Simple and what makes this code better is that you can use it in a JavaScript file separately and have it fairing to more then one file with the same popup size even though its different pages on popups.
Javascript
// Popup window code
function MyPopUp(url) {
popupWindow = window.open(
url,'popUpWindow','height=454,width=580,left=0,top=200,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes')
}
HTML
My PopUp
NOTE: You can also use this as onload in body for example <body onload="JavaScript:MyPopUp('MyDirectory/Page.html');"> and it will aslo work on onmouseover and others... though I do not advise this unless you want to piss off the clients visiting your page.
I have a script tag like
<div id='CommentBox'></div>
<script src="http://www.mywebsite.com/widget.js" type="text/javascript" />
This javascript creates a comment box. (like facebook comment box)
But when users copy/paste same exact script tag more than once Chrome and IE9 does not request 2nd, 3rd file again, because it is cached. But actually people want to use comment box more than once in the same page. How can I break browser cache and force it to download as many as people pasted in their blog?
You're doing it wrong.
If you want two or more comment boxes just call the code twice. A script include is not like a function call.
Instead of Code that you write use this code:
Main HTML File:
<html>
<head>
<script src="http://www.mywebsite.com/widget.js" type="text/javascript" />
</head>
<body>
<div id="CommentBox"></div>
<script type="text/javascript">
Func1();
</script>
</body>
</html>
widget.js File:
function FUNC1(){
alert("Hello");
}
*Update: Ultimately I've decided that accomplishing exactly what I want here isn't possible due to the issues it poses to security. Kalle's answer below gives a solution that is closest to what I want to accomplish.
In order to solve my problem I've created scripts on both pages and will use a sort of push notification that is routed through the server in order for them to communicate.
Thanks for the help!! *
I have two pages. Both windows already exist independently. Page two has a function declared in JS.
I would like to be able to call the function in window two by clicking a link in window one.
Page 1:
<html>
<head>
<title>This is a title!</title>
</head>
<body style="background: lightblue">
Click Me!
</body>
Page 2:
<html>
<head>
<META HTTP-EQUIV="Window-target" CONTENT="my_target" />
<title>This is a title!</title>
<script type=text/javascript>
function clicked() {
alert('test');
}
</script>
</head>
<body style="background: lightblue">
</body>
Since it is on the same domain you can get this to work but would have to change the way you were doing it a little.
First off you would have to open it in a popup using this syntax rather than a new tab:
newwindow=window.open(url,'name','height=200,width=150');
and then you could simply call newwindow.clicked() after the popup is called.
update
just did a quick test and this will open it in a new tab. (sorry its been a while since I used the open function.
newwindow=window.open(url,'name');
Just noticed also that you should wait for the popup to load. So in my Example it would look a little something like this (with jQuery):
var newwindow = window.open('http://www.tylerbiscoe.com/vb/new.html');
$(newwindow).load(function(){
newwindow.clicked();
});
Ok, brand new answer. I hope this is what you were thinking. This is however, when you open page 2 from page 1.. So basically, page 1 would know who page 2 is..
Online example: http://kopli.pri.ee/stackoverflow/6832271.php
Page 1
<html>
<head>
<title>Page 1</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<style>
.ajaxlink {color: blue; cursor: pointer; border-bottom: 1px dotted blue;}
</style>
</head>
<body>
<span id="open_page_2" class="ajaxlink">Open new window</span>
<br>
<br>
Click Me!
<script>
$('#open_page_2').click(function(){
child = window.open('test2.php','page_2','width=600,height=600');
});
$('a[target=my_target]').click(function () {
child.SecondPageFunction();
return false;
});
</script>
</body>
</html>
Page 2
<html>
<head>
<title>Page 2</title>
</head>
<body>
<h1>Your seeing page 2!</h1>
<script>
function SecondPageFunction () {
alert('Second page action got triggered!');
}
</script>
</body>
</html>
The script must be a part of the page you're opening in the new window. You're absolutely correct about it being a security flaw if it was elsewise allowed.
You could add some query string argument that could be picked up onload by javascript in the page you are opening and call your function if the query string arg is present.
On my site a number of operations can take a long time to complete.
When I know a page will take a while to load, I would like to display a progress indicator while the page is loading.
Ideally I would like to say something along the lines of:
$("#dialog").show("progress.php");
and have that overlay on top of the page that is being loaded (disappearing after the operation is completed).
Coding the progress bar and displaying progress is not an issue, the issue is getting a progress indicator to pop up WHILE the page is being loaded. I have been trying to use JQuery's dialogs for this but they only appear after the page is already loaded.
This has to be a common problem but I am not familiar enough with JavaScript to know the best way to do this.
Here's simple example to illustrate the problem. The code below fails to display the dialog box before the 20 second pause is up. I have tried in Chrome and Firefox.
In fact I don't even see the "Please Wait..." text.
Here's the code I am using:
<html>
<head>
<link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.dialog.js"></script>
</head>
<body>
<div id="please-wait">My Dialog</div>
<script type="text/javascript">
$("#please-wait").dialog();
</script>
<?php
flush();
echo "Waiting...";
sleep(20);
?>
</body>
</html>
You'll need to run that piece of code immediately after your <body> tag, something like:
<html>
<head>
</head>
<body>
<div id="please-wait"></div>
<script type="text/javascript">
// Use your favourite dialog plugin here.
$("#please-wait").dialog();
</script>
....
</body>
</html>
Note I omitted the traditional $(function (){}) because you need this to be loaded as soon as the page is shown, not after the whole DOM is loaded.
I've done this before and works great, even if the page has not finished loading yet.
EDIT: you'll have to be certain the jQuery dialog plugin you're using is loading before your entire DOM loads. Usually this is not the case, you it won't work. In that case, you'll need to use a g'old plain JavaScript solution, such as Lightbox 1 or Lightbox 2.
