I have two examples using setTimeout(). This one works:
<html>
<head>
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type="text/javascript">
google.load('visualization','1',{packages:['table']});
function start() {
setTimeout(ShowClipboardContent, 2000);
}
function ShowClipboardContent() {
var data = new google.visualization.DataTable(window.clipboardData.getData('Text'));
var table = new google.visualization.Table(document.getElementById('div'));
table.draw(data,{showRowNumber: true});
}
</script>
</head>
<body>
<button onclick='start();'>Show text data in clipboard</button>
<div id='div'></div>
</body>
</html>
But this doesn't:
<!DOCTYPE html>
<html>
<head>
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization','1',{packages:['table']});
</script>
<script type='text/javascript'>
//runs powershell and copies output onto clipboard
function powershell(t) {
//object that will execute powershell
var run = new ActiveXObject("Shell.Application");
//breaks the list of servers into array
var servers = t.textarea.value.split('\n');
//script that powershell will run
var script = 'some powershell command';
//path to powershell.exe
var program = 'C:\\Windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe';
//putting it all together
run.ShellExecute(program,script,'','open','1');
setTimeout(drawTable, 10000);
}
//draws data table using data from clipboard
function drawTable() {
var data = new google.visualization.DataTable(window.clipboardData.getData('Text'));
var table = new google.visualization.Table(document.getElementById('table'));
table.draw(data, {showRowNumber: true});
}
</script>
</head>
<body>
<div id='form'>
<form>
Enter name(s):<br />
<textarea id='textarea' style='width:20%; height:500px;'></textarea><br />
<button onclick='powershell(this.form)'>Query</button>
</form>
</div>
<div id='table'></div>
</body>
</html>
Just to reiterate: the problem is that setTimeout() won't work on the second code but works on the first one and I would like to know why because I see no difference.
try to add a
console.log(drawTable);
just before your timeout. if it returns 'function', it'a good, your timeout will be ok. if not return anything, your activeX script should break the code

I need to save the source code of any website in a java script variable. For example, saving Google source code in a variable "GoogleSourceCode".
I tried some ways but I don't have enough knowledge for that.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.12.1.min.js"></script>
</head>
<body>
<div id="container">
<button id="acessaSite">Acessa Site</button>
<button id="pegarHTMLagora">pegar HTML agora</button>
</div>
<script>
$('#acessaSite').on('click', function () {
$.getJSON('http://www.whateverorigin.org/get?url=' + encodeURIComponent('https://google.com.br') + '&callback=?', function(data){
alert(dados.conteudo);
});
});
$('#pegarHTMLagora').on('click', function () {
var htmlAgora = document.documentElement.innerHTML; // Javascript vanilla (sem jquery)
alert(htmlAgora);
});
let htmlPego = document.documentElement.innerHTML;
</script>

Using jsPDF, currently attempting to do the following:
Define downloadPDF function
Generate PDF document with "Hello world" string
Download PDF document
Declare a button with an onclick that calls downloadPDF()
<html>
<head>
<title>Page Title</title>
<script type="text/javascript" src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="//mrrio.github.io/jsPDF/dist/jspdf.debug.js"></script>
</head>
<body>
<script>
function downloadPDF() {
var doc = new jsPDF('p', 'in', 'letter');
doc.text('Hello world', 10, 10);
doc.save('myPDF');
}
</script>
<button onclick="downloadPDF()" class="button">Run Code</button>
</body>
</html>
But the PDF document turns out to be empty.
Any ideas ?
What are the arguments that you're passing to the jsPDF constructor supposed to do? Removing them worked for me:
var doc = new jsPDF();

I'm trying to replace the context of a loaded element with the following code:
$("#menu1").load("./templates/menu.html");
var str = $("#menu1").html();
alert(str);
str.replace("[number]", "1");
$("#menu1").replaceWith(str);
But I always get an empty str, the menu1 gets loaded correctly with the menu.html content so I have no idea what's going on.
You need to test the string after the load - the way you have done it, it can be run whilst the load is still going. Try this:
$("#menu1").load("./templates/menu.html", function() {
var str = $("#menu1").html();
alert(str);
str.replace("[number]", "1");
$("#menu1").replaceWith(str);
});
More information
$("#menu1").load("./templates/menu.html", function(){
//complete
var str = $("#menu1").html();
});
Loading part isn't instant so you are trying to apply var str = $("#menu1").html(); before load() has time to complete
You need to do the task in callback function of load:-
For example :-)
<!DOCTYPE html>
<html>
<head>
<script data-require="jquery#*" data-semver="2.1.3" src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
Hello this is rachit 1 1 1 1.
<div id="menu1"></div>
<script>
$("#menu1").load("index.html", function() {
var str = $("#menu1").html();
alert(str);
str.replace("[number]", "1");
$("#menu1").replaceWith(str);
});

I'm using HTML publisher in hope to have a html page with some javascript codes running on hudson. The HTML code is like this:
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="../stringformat.js"></script>
<script type="text/javascript">
......
sql=String.format("/.csv? select from table where exchange=`ABC......")
</script>
</head>
However, after a successful build, my html page doesn't show what it suppose to, and as I check the error console, it says
Error: TypeError: String.format is not a function
I have put my stringformat.js into the top folder, as the HTML publisher doesn't seem to allow the file to contain anything other than HTML files.
Can anyone tell me why the String.format is not loaded properly? Thanks!
PS: stringformat.js is the file i got from
http://www.masterdata.se/r/string_format_for_javascript/
The code should be working properly as this piece of code works outside the hudson
try code:
<html>
<head>
<title>String format javascript</title>
<script type="text/javascript">
String.format = function() {
var s = arguments[0];
for (var i = 0; i < arguments.length - 1; i++) {
var reg = new RegExp("\\{" + i + "\\}", "gm");
s = s.replace(reg, arguments[i + 1]);
}
return s;
}
var _myString = String.format("hi {0}, i'am {1}","everybody", "stackoverflower");
function show(){
alert(_myString);
}
</script>
</head>
<body>
<input type="button" name="btnTest" id="btnTest" value="Test string format" onclick="show();" />
</body>
</html>
If I introduce the jquery.js into the page twice(unintentional OR intentional), what will happen?
Is there any mechanism in jquery that can handle this situation?
AFAIK, the later one jquery will overwrite the previous one, and if there is some action binding with the previous one, it will be cleared.
What can I do to avoid the later one overwrite the previous one?
===edited===
I couldn't understand WHY this question got a down vote. Could the people who give the down vote give out the answer?

u r right, now it's the test code:
<html>
<head>
</head>
<body>
fast<em id="fast"></em><br>
slow<em id="slow"></em><br>
<em id="locker"></em>
</body>
<script type="text/javascript">
function callback(type){
document.getElementById(type).innerHTML=" loaded!";
console.log($.foo);
console.log($);
console.log($.foo);
$("#locker").html(type);
console.log($("#locker").click);
$("#locker").click(function(){console.log(type);});
$.foo = "fast";
console.log($.foo);
}
function ajax(url, type){
var JSONP = document.createElement('script');
JSONP.type = "text/javascript";
JSONP.src = url+"?callback=callback"+type;
JSONP.async = JSONP.async;
JSONP.onload=function(){
callback(type);
}
document.getElementsByTagName('head')[0].appendChild(JSONP);
}
</script>
<script>
ajax("http://foo.com/jquery.fast.js", "fast");
ajax("http://foo.com/jquery.slow.js", "slow");
</script>
</html>
it produced the result:
undefined test:12
function (a,b){return new e.fn.init(a,b,h)} test:13
undefined test:14
function (a,c){c==null&&(c=a,a=null);return arguments.length>0?this.bind(b,a,c):this.trigger(b)} test:16
fast test:19
undefined test:12
function (a,b){return new e.fn.init(a,b,h)} test:13
undefined test:14
function (a,c){c==null&&(c=a,a=null);return arguments.length>0?this.bind(b,a,c):this.trigger(b)} test:16
fast
the token "$" of the previous one(jquery.fast.js) is overwrite by the later(jquery.slow.js) one.
Is there any method to avoid the overwriting?
I did try this code:
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(function() {
$('#try').click(function() {
alert('ok');
});
});
</script>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<button id="try">Try me</button>
</body>
</html>
Nothing happend. On click I've got an alert. Same result if the second jquery.js loaded in body tag before or after the button.
