So I tried this. I put the required code in the head:
<script type="text/javascript">
var callback = function(formatted_number, mobile_number) {
var e = document.getElementById("number");
e.innerHTML = "";
e.appendChild(document.createTextNode(formatted_number));
};
</script>
And then instead of using:
<body onload="_googWcmGet(callback, '0800-123-4567')">
<span id="number">0800-123-4567</span> </body>
I'm using:
<body> <span id="number">0800-123-4567</span> <script type="text/javascript">
window.onload = _googWcmGet(callback, '0800-123-4567'); </script> </body>
It errors out with _googWcmGet being undefined. Think this is due to my lack of knowledge of JS/DOM stuff and that I need to cal _googWcmGet outside the body tag some other way?

I have a variable of the form :
var x = '<script type="text/javascript" language="javascript"> ..lots of stuff...</script>
<script type="text/javascript" language="javascript"> ..even more of stuff...</script>'
and I want to insert it with jquery into my HTML code and execute it.
I tried using the append, html and eval without any luck.
Any ideas?
sample script:
<script type="text/javascript" language="javascript">
var clk = 'http://......';
</script>
<script type="text/javascript" language="javascript" src="http://...."></script>
<noscript>
<img src="http://..." width="120" height="600" border="0" alt="">
</noscript>
this will in the end show an img, which will load asynchronously.
Usually having </script> tags nested within other <script></script> tags will break things. You'll need to split them up like in the Javascript below to not cause browser issues.
Here is a working fiddle:
https://jsfiddle.net/2vrfxrse/
Javascript
var jsCode = '<scr' + 'ipt>var executeTest = function(){ alert("This is a test."); }</scr' + 'ipt>';
$('head').append(jsCode);
HTML
<script>executeTest();</script>
This solution will probably work for your specific scenario:
var rx = new RegExp("<script .*?>(.*?)<\/script>", 'g');
var x = '<script type="text/javascript" language="javascript">alert("..lots of stuff...");</script><script type="text/javascript" language="javascript">alert("..even more of stuff...");</script>';
var res = rx.exec(x);
while (res) {
var s = document.createElement("script");
s.appendChild(document.createTextNode(res[1]));
document.body.appendChild(s);
res = rx.exec(x);
}

You can use Jquery getScript:
//Moment example
if (typeof moment == "undefined") {
var url = "~/assets/js/moment.js";
$.getScript(url);
}
Or Jquery Function:
$(function(){
var test = "this.Foo = function() {alert('hi');}";
var F=new Function (test);
(new F()).Foo(); //Shows "Hi" alert
});
$(function(){
var test = "this.Foo = function() {alert('hi');}";
var F=new Function (test);
(new F()).Foo(); //Shows "Hi" alert
});

An extremely simple question but I am noob. I have been learning javascript and jquery for a while on jsfiddle, there everything works fine, building cool quizzes and all, but when I tried to actually create a directory, reference the jquery library and my javascript file, nothing works, even the below code, when saved as an HTML file doesn't work. I just paste it into notepad and save it as html, when I open it with it doesn'T work.
<html>
<head>
<title>webpage</title>
<script type="text/javascript">
window.onload = function() {
var myDiv = document.getElementById('#div');
myDiv.appendChild(document.createTextNode("Hi my name is Mehmetcan"));
}
</script>
</head>
<body>
<div id="myDiv"> </div>
</body>
</html>
Use this as starting point:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<title>webpage</title>
<script type="text/javascript">
$(document).ready(function () {
var myDiv = document.getElementById('myDiv');
myDiv.appendChild(document.createTextNode("Hi my name is Mehmetcan"));
});
</script>
</head>
<body>
<div id="myDiv"> </div>
</body>
Another approach that doesn't rely on JQuery but on pure, vanilla javascript.
<html>
<head>
<title>webpage</title>
<script type="text/javascript">
document.body.onload = loadSite;
function loadSite() {
var newDiv = document.createElement("span");
var newContent = document.createTextNode("Hi there and greetings!");
newDiv.appendChild(newContent);
myDiv.appendChild(newDiv);
}
</script>
</head>
<body>
<div id="myDiv"> </div>
</body>
</html>
You can find the full javascript sample as well as more information here, on the document.createElement MDN pages.
document.body.onload = addElement;
var my_div = null;
var newDiv = null;
function addElement () {
// create a new div element
// and give it some content
var newDiv = document.createElement("div");
var newContent = document.createTextNode("Hi there and greetings!");
newDiv.appendChild(newContent); //add the text node to the newly created div.
// add the newly created element and its content into the DOM
my_div = document.getElementById("org_div1");
document.body.insertBefore(newDiv, my_div);
}
I am testing putting a text editor on my page and storing it as part of a JSON object.
HTML
<!DOCTYPE html>
<html>
<head>
<script src="http://tinymce.cachefly.net/4.0/tinymce.min.js" type="text/javascript"> </script>
<script type="text/javascript">
tinymce.init({
selector: "textarea"
});
</script>
<link rel="stylesheet" href="/jquery.mobile-1.3.2.min.css"/>
<script src="/jquery-1.9.1.min.js"></script>
<script src="/jquery.mobile-1.3.2.min.js"></script>
</head>
<body>
<form method="post" action="formSubmit.js">
<textarea name ="editor"></textarea>
<p><input type="submit" value="Submit"></p>
</form>
</body>
</html>
JS
$(document).ready(function () {
var text = $("editor").val();
var name = "project name";
var id = 5;
var item = new item(name, text, id);
var itemArray = localStorage.items;
if (itemArray == undefined) {
itemArray = [];
} else {
itemArray = JSON.parse(itemArray);
}
itemArray.push(item);
localStorage.items = JSON.stringify(itemArray);
});
I want to be able to store item in a JSON object. When I run this I receive a "not-well formed" error at line 1 of the Javascript. It's a very simple program I'm running and can't seem to pinpoint what is causing the error. Is the JSON done incorrectly or are scripts in my HTML header causing issues?
$("editor") is looking for an html tag called 'editor'. you probably want to attach an id attribute to your and do $('#editor')
Say I have the following JavaScript in a HTML page
<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
</script>
<body>
<a href = test.html>I need the value of "splitText" variable here</a>
</body>
</html>
How do I get the value of the variable "splitText" outside the script tags.
Thanks!
<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
window.onload = function() {
//when the document is finished loading, replace everything
//between the <a ...> </a> tags with the value of splitText
document.getElementById("myLink").innerHTML=splitText;
}
</script>
<body>
<a id="myLink" href = test.html></a>
</body>
</html>
Try this :
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
$("#target").text(splitText);
});
</script>
<body>
<a id="target" href = test.html></a>
</body>
</html>
<html>
<head>
<script>
function putText() {
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
document.getElementById("destination").innerHTML = "I need the value of " + splitText + " variable here";
}
</script>
</head>
<body onLoad = putText()>
<a id="destination" href = test.html>I need the value of "splitText" variable here</a>
</body>
</html>
In raw javascript, you'll want to put an id on your anchor tag and do this:
<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
function insertText(){
document.getElementById('someId').InnerHTML = splitText;}
</script>
<body onload="insertText()">
I need the value of "splitText" variable here
</body>
</html>
Here you go: http://codepen.io/anon/pen/cKflA
Although, I must say that what you are asking to do is not a good way to do it. A good way is this: http://codepen.io/anon/pen/jlkvJ
The info inside the <script> tag is then processed inside it to access other parts. If you want to change the text inside another paragraph, then first give the paragraph an id, then set a variable to it using getElementById([id]) to access it ([id] means the id you gave the paragraph).
Next, use the innerHTML built-in variable with whatever your variable was called and a '.' (dot) to show that it is based on the paragraph. You can set it to whatever you want, but be aware that to set a paragraph to a tag (<...>), then you have to still put it in speech marks.
Example:
<!DOCTYPE html>
<html>
<body>
<!--\|/id here-->
<p id="myText"></p>
<p id="myTextTag"></p>
<script>
<!--Here we retrieve the text and show what we want to write...
var text = document.getElementById("myText");
var tag = document.getElementById("myTextTag");
var toWrite = "Hello"
var toWriteTag = "<a href='https://stackoverflow.com'>Stack Overflow</a>"
<!--...and here we are actually affecting the text.-->
text.innerHTML = toWrite
tag.innerHTML = toWriteTag
</script>
<body>
<html>
I would like to know how to pass the value of a variable in JavaScript file to a variable in a script function which is written on top of the HTML file.
I wrote it like this:
myjsfile.js:
var abc = "10";
HTML file:
<html>
<head>
<script type="text/javascript">
(function() {
var test = document.createElement('script'); test.type = 'text/javascript'; test.async = true;
test.src = 'testquery.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(test, s);
alert(abc);
})();
</script>
</head>
<body>
</body>
</html>
I am not getting the output. Please help! Thanks in advance.
Basically I am trying to create a jquery plugin just like Google analytics.
The script has to load first, try using onload
test.onload=function(){alert(abc);}
<html>
<head>
<script type="text/javascript" src="testquery.js"></script>
<script type="text/javascript">
alert(abc);
</script>
</head>
<body></body>
</html>
try this:
(function() {
var test = document.createElement('script');
document.getElementsByTagName('head')[0].appendChild(test);
test.type = 'text/javascript';
test.src = 'testquery.js';
test.onload = function () {
alert(abc);
}
})();
well.. the onload has already been told but you should at least switch your way of appending it to the head.
