I have some JavaScript code with Servlets code, I want to move all of them (between ) to external js file, but it doesn't work, what can I do? How to modify my code if only part of JavaScript can move to external file.
<script language="JavaScript" type="text/JavaScript">
var sel = document.getElementById('sel');
var selList = [];
<%
String key = "";
String text = "";
for(int i = 0; i < master.size(); i++) {
Map option = (Map) master.get(i);
key = (String) option.get("Code");
text = key + " " + (String) option.get("NAME");
%>
selList.push({
key: "<%=key%>",
text: "<%=text%>"
});
<%
}
%>
</script>
Here two options:
1-by not using ajax
external.js
var images;
function renderImages(){
//do things for showing images here.
//images variable has images data as JSON (i suggest you this way) so you can easily iterate over list and render it.
}
jsp
<html>
<head>
<script type="text/javascript" src="external.js"></script>
<script>
images = "<%=request.getAttribute("imageDataAsJSON")%>"; //here i assume you populate request variable with your image data in JSON format. Be careful about parse errors due to ' and ".
</script>
</head>
<body>
<script>
renderImages();
</script>
</body>
</html>
2-by using ajax (you can seperate client side logic into external js code and populate data into it by doing ajax calls to server side.)
external.js
function renderImages(){
//do ajax to your servlet which returns image data as JSON.
//iterate over image data and render your html elements accordingly.
}
jsp
<html>
<head>
<script type="text/javascript" src="external.js"></script>
</head>
<body>
</body>
</html>

I would like to check using liquid language, if is there somewhere in the page, a script being called twice or more.
For example:
<script src="myscripts.js"></script>
<script src="myscripts.js"></script>
Is it possible using liquid or should I use javascript to validate?
I'm not sure about liquid, but if you wanted to go the JS route, this could work:
//locate all `<script>` tags and save the elements into an array
var scriptTags = [];
document.querySelectorAll('script').forEach(function(tag) {
scriptTags.push(tag)
});
//Put just the URLs of the script tags into an array
var scriptUrls = scriptTags.map(function(tag) {
return tag.src;
});
//Get a list of any URL that appears more than once
var duplicateUrls = scriptUrls.filter(function(url, i) {
return scriptUrls.indexOf(url) != i;
});
console.log(duplicateUrls);
<script src="dupe.js"></script>
<script src="other1.js"></script>
<script src="dupe.js"></script>
<script src="other2.js"></script>
<script src="other3.js"></script>
I'm trying to get the html of www.soccerway.com. In particular this:
that have the label-wrapper class I also tried with: select.nav-select but I can't get any content. What I did is:
1) Created a php filed called grabber.php, this file have this code:
<?php echo file_get_contents($_GET['url']); ?>
2) Created a index.html file with this content:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<meta charset=utf-8 />
<title>test</title>
</head>
<body>
<div id="response"></div>
</body>
<script>
$(function(){
var contentURI= 'http://soccerway.com';
$('#response').load('grabber.php?url='+ encodeURIComponent(contentURI) + ' #label-wrapper');
});
var LI = document.querySelectorAll(".list li");
var result = {};
for(var i=0; i<LI.length; i++){
var el = LI[i];
var elData = el.dataset.value;
if(elData) result[el.innerHTML] = elData; // Only if element has data-value attr
}
console.log( result );
</script>
</html>
in the div there is no content grabbed, I tested my js code for get all the link and working but I've inserted the html page manually.
I see a couple issues here.
var contentURI= 'http:/soccerway.com #label-wrapper';
You're missing the second slash in http://, and you're passing a URL with a space and an ID to file_get_contents. You'll want this instead:
var contentURI = 'http://soccerway.com/';
and then you'll need to parse out the item you're interested in from the resulting HTML.
The #label-wrapper needs to be in the jQuery load() call, not the file_get_contents, and the contentURI variable needs to be properly escaped with encodeURIComponent:
$('#response').load('grabber.php?url='+ encodeURIComponent(contentURI) + ' #label-wrapper');
Your code also contains a massive vulnerability that's potentially very dangerous, as it allows anyone to access grabber.php with a url value that's a file location on your server. This could compromise your database password or other sensitive data on the server.
We are working with the facebook api and have stored the data retrieved in a JSON format into an array. We would like to display this information in a different HTML page but are unable to do so, please help regarding this?
<p id="demo"></p>
<script> var str=""; var names1 = new Array(); //creating names1 array
getFriendsList = function() { //calling from another function
FB.api('me/taggable_friends', function(response) {
for (var i = 0; i <= response.data.length; i++) {
names1.push(response.data[i].name); str=str+"<br>"+"<br>"+names1[i]; //appending thenames to str
document.getElementById("demo").innerHTML = str;//displaying the element in the html page.
}
});
} </script>
I am still a little confused by your question, but I am assuming that you want to know how to display the elements from an array onto your HTML page.
If this isn't what you are asking, then just expand on your question and I will see how I can help.
Explanation for code below
You are accessing your JavaScript file in your HTML by adding the <script type="text/javascript" src="app.js"></script> reference.
The JavaScript is creating a simple array called myArray. We then loop through our array and display content using the document.write(...); line.
HTML
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
</body>
</html>
JavaScript
var myArray = [1, 2, 3];
// for each loop
for (var i in myArray) {
document.write(myArray[i]);
}
I have a separate javascript file(buy.js) from my html file(pay.php) that the html file posts to once a form is submitted. However, there are some javascript variables in pay.php that are outside the scope of the form that I need to call in the separate javascript file (buy.js). Is this possible to do?
This is the snippet of javascript that I need to access in my html file (buy.js):
var planTerm = term;
This is the javascript in the html that I need the separate javascript file to access (pay.php):
var term = 0;
var price = 0;
function updatePrice(e) {
price = parseFloat(select.value);
if (price == select.options[1].value){
term = 12;
} else if (price == select.options[2].value) {
term = 1;
}
}
Here is a Pastie of all the code.
Using PHP you can simply do (using the include() function):
include("File.php");
So, as my example goes,
The JS_INCLUDE.php File:
<html>
<body>
<script>
var JSvar = "This is a external JS var.";
</script>
</body>
</html>
The index.php
<html>
<body>
<?php
include("JS_INCLUDE.php");
?>
<script>
document.write(JSvar);
</script>
</body>
</html>
But of course if the .php file is remote from the directory, you cannot.

I am trying to create a javascript quiz, that gets the questions from a xml file. At the moment I am only starting out trying to parse my xml file without any success. Can anyone point me to what I am doing wrong?
<html>
<head>
<title>Test</title>
<script type="text/javascript" src="prototype.js"></script>
</head>
<body>
<div class="spmArr">
</div>
<script type="text/javascript">
var quizXML = '<quiz><Sporsmal tekst="bla bla bla"/><alternativer><tekst>bla</tekst><tekst>bli</tekst><tekst correct="yes">ble</tekst></alternativer><Sporsmal tekst="More blah"/><alternativer><tekst>bla bla</tekst><tekst correct="yes">bli bli</tekst><tekst>ble ble</tekst></alternativer></quiz>'
var quizDOM = $.xmlDOM( quizXML );
quizDOM.find('quiz > Sporsmal').each(function() {
var sporsmalTekst = $(this).attr('tekst');
var qDiv = $("<div />")
.addClass("item")
.addClass("sporsmal")
.appendTo($(".spmArr"));
var sTekst = $("<h2/>")
.html(sporsmalTekst)
.appendTo(qDiv);
});
</script>
</body>
</html>
When I try this in my browser the classes and div are not being created. And the page is just blank. Am i doing something wrong when I intialize the xml?
edited to add prototype.js and close function
Looks like you're forgetting to close your .each call. append ); after the statement for sTekst and your call will parse correctly.
