I've been using JavaScript for a few years now I'm not a huge expert I rely more of JQuery. I am just wondering what best solutions are there to call Javascript files (and to make pages load faster):
Normally I request all these in the Header like you normally would but I have seen and heard people to call their Javascript files in the footer to make page load faster and have all their Javascript functions all in the footer as well.
Is this a good idea? What are the downside? Should I just keep all my JS in the Header as usual?
What I would like to do is create header and footer information for my webpages which are created by calling from a referenced .js page . . . for example in Header.js:
is there a way to rid of the page header (usually it's the page title and url) and the page footer (usually it's the page number and date) without having user to change from the web browser's the page setup ?
Can this be done using javascript or just html meta tags?
Also we control the contents of what is printed from a web page without having to redirect the page? Example, I have three paragraphs on a web page and I don't want the middle paragraph to be printed.
I have a database driven website, which shows a list of files that have been uploaded by users. I have a script called controller.php, which generates the HTML:
This is my first message and I am extremely new to jQuery. I am using Ajax to call external html pages into a div in my site. I have three external html forms which uses JavaScript and one .file. When I call these pages, the html pages are being rendered correctly but the JavaScript and .pl file (form post) is not being executed. Any ideas on how to resolve?
I have a custom object named #cdata-section, however I am unable to access this object and get a run time "Illegal Character" javascript error. my object looks like this:
data.news.story[i].body.#cdata-section
The pound sign is causing problems. How can I use this object in my javascript source? Right now I'm trying something like this to escape the pound sign:
Lets say you have a 1000 line javascript file which is linked to an everyday html file. The browser is set, by default, cache the linked javascript file (after downloading and interpreting it).
But once it's cached and put into a temp directory on the client's computer, is the cached file in an already parsed format? Or something relative? Or is it in the same format as it was on the server-side? This would mean that the .js file is parsed each time the exact same way (as long as the file itself is not changed, deleted, or renewed on the server-side).
I have been struggling with a cross browser solution to loading external javascript files on the fly.
I have been successful using the following code in IE6:
var newScr = document.createElement("SCRIPT"); newScr.src = "newScr.js"; newScr.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(newScr);
I believe the reason is that IE is loading the external file syncronously while Firefox is not. Is there an onload event for creating an element (if so I do not see it in Venkman). I have seen the solution of using XMLHTTP to load the script but I am trying to get around any dependency (atleast at this stage of the library) on activex.
4. In Firefox, it works beautifully ( no shock ) 5. In IE it does not ( no shock ) 6. If i put the function in inline <scripttags in my HTML, the JS runs fine (no syntax error).
I need a way of loading api scripts on the fly. ie. if the user clicks on a link the javascript would suck in the api script depending on what the user has selected. By api script I mean:
I am using the maps24 api to build an address finder - ie. put your postcode/zipcode in and populate the rest of the address details. For some reason you need to load a different js file for each region (north america, europe, etc). I want my users to click on their region and have the <script> tags inserted into the head. I have done this using javascript but the functions don't seem to be available. I am assuming that the page needs to refresh??
Does anyone know away of making the javascript functions available to use without having to refresh the page? In other words, loading javascript files on the fly.
I have Declared same function and two diff javascript files and both files are included in HTML page and one more same function declared in HTML code too... So problem is that, which function will execute first, i mean function in either javascript or function in HTML Code?
We have a directory of files on our ftp server. Is there a javacript to make a connection to the ftp server and compare files on a local drive and on the server? Files that have been changed or added need to be copied across from the ftp server to the local drive.
I have a problem of client side XSL transformation. I sent the XML and the XSL to the client in XML data islands. Using the transform Node method the HTML is returned. There is however some script tag in the XSL file which references external ..js files they are like
Now, after transformation the function from this .js file are not called and object required errors are thrown. This is despite the fact that IE has downloaded the .js file and they are visisble in the cache (Temporary Internet Files). This problem only occurs if the .js file is not present in the cache, hence it happens when the user visits some site for the first time.
I am working on a website that uses a random header. I have been trying to figure out how to adjust the code so that the header also serves as a clickable link.
Here is the code that I have:
What do I need to add in order for the header to also serve as a link? I am completely new to JavaScript and I don't understand it very well.
I have designed a mail service in java.In my compose page,i want to attach some excel files of text files and to send it.After sending i want to store it my database.Then how can i download or open that file after opening that recipient mail inbox.
I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.The script works fine when the requested XML file is stored on the same server as the script.The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
Code:
window.onload = initAll; var xhr = false; function initAll() { document.getElementById("makeTextRequest").onclick = getNewFile;
In my quest to implement ajax for the first time i've hit a brick wall. i've been searching for hours for a solution but with no success. Here is the problem.
[Code]...
why is it not working? my PHP code is outputting the contents of the xml document.
I want to write a javascript to list of all files in a folder including files in the subfolders. This is for the scorm purpose to list all the files. some examples are listing files but not listing the files inside the subdirectories. I want the file's full path like C:Documentsjavascriptwilson.js like this.
First let me describe the problem. I have an HTML form that in one field has an onBlur call to a JavaScript function. When you exit the field, it calls the JavaScript routine, which in turn calls a PHP script. The PHP script runs returns the value needed. And returns to the JavaScript. The JavaScript function is then supposed to set alerts depending on the values returned from the PHP script. It doesn't. If you then move the cursor into the field and exit again, it again runs the JavaScript which calls the PHP script then proceeds to show the alerts exactly like it is supposed to.
I did some experimenting, and if you use a button to run the JavaScript, the exact same thing happens. Click the button and the PHP script sends back the value, but no alert. You click the button a second time, and the alert shows.
I am using the JavaScript monitor in FireFox v1.5 so I can see that the PHP script is being called and returning the correct value the first time. So what I am trying to figure out is why the routine has to be called twice before I get my alert.
Below is the HTML, JavaScript & PHP that I am using....
I have four folders and each folder has one images, let say ( images-one.jpg, images-two.jpg, images-three.jpg, images-four.jpg). now,in index.php page there are four buttons, each buttons for each images. if i clicked button numer two for images-two.jpg, and then it will show that images name from that folder in index.php page. and then if i reload same index.php page or refreshed same page, i want to show SAME images that I clicked before which is images-two.jpg. how can i write that code to show images from four files, each files are in each folder.
I ve a aspx page with a textbox.I have created the Text_Changed event for this textbox.We know that , this will be fired when we enter any text in that textbox and pressing the enter key.quite natural.

I am trying to call a java method from within my Javascript, but cannot seem to get it to work. All the examples I have found online and in the forums are using Java applets. I have a method that I want to call that does a search, and produces a message dialog displaying the results. Also, the class file lives next to the html file. How would I invoke this in my code? This is what I have now:
