I've noticed that if you declare a variable in one function, then call another function, the variables cannot be accessed in that function. Is there any way to get the value of a variable declared in a different function?
I'm new here, and new to js. Here is my problem: I have written out a code to make an image switch from state 0 to 1 and back to 0 again (an eye blink). The code works fine, but I would like to write the functions with arguments so it could be applied to more images. I have tried for a few hours (and searched forums) and am getting no where. Here's my code.
Code: function home_blinkDown() { //alert('blink down'); var t = setTimeout("home_blinkSwap('home_js', 'images/main/home_blink.png')", 2000);
I'm sure there is a really, really simple way to solve this issue. I'm just not a programmer so I don't know it off the top of my head. I have this script ext.php that accepts a variable ref.[URL]..The problem is that there is also a '?' in the variable ref that I'm using. Like so:[URL]...I suspect because there is another '?' in variable ref, ext.php has a problem with it. I cannot change ext.php or sitename.asp.
So my question is, how can I make this work properly via the url? I've tried using %26 for the '?' as well as the & html escape code, but it still doesn't work.
I cannot findout how I can write to global variables in a a JQUERY function. <script type="text/javascript"> function checkusername (username ) { $.post("[URL]", { action: 5, username: username }, function(xml) { result = $("apot", xml).text(); //<-- this variable is not global... why ?? message = $("message", xml).text(); //<-- this variable is not global... why ?? alert(message); //<--here variables are shown ok alert(result); }); alert(message); //<--here variable is NULL !! alert(result); //<--here variable is NULL !! } </sctipt>
I'm trying to trap a user entry that cannot be found in the database. When a code is entered, the page should give a "Code Not Found" message if it is an undefined value.
However, it didn't; and it always shows the "undefined" value to the page instead.
function doSomthing(arrayset1, arrayset2, nutherVariable){ document.theForm.txtBox.value=arrayset1[n] + arrayset2[n]; <!-- No output to form textfield unless array defined within function--> } </Script> </Head> <Body> Passes and recieves variables to/from function(s) via Form </Body
I think what I am asking is what is the syntax to do this.
I am new to Javascript and have searched the forums and can't seem to find the missing link. I have 3 radio groups, each button has a $ value, and I merely want to display the amounts that are selected from each group. I have the page up that you can view it to get a better idea code...
When I press the submit button I want it to tell me if a button has been pushed in a certain group the amount that was selected. When I press the button now nothing happens.
Looking at the preview I have used the [CODE] tags but it appears it is only allowing it on one continuous line. Please tell me how to fix that and I can change it before someone trys to debug the code.
I'm creating a small e-commerce store where things live coupon activation will be done on the client side(That's without loading the page). My problem is that I don't know how to pass the coupon deduction to another page using javascript. Is there a way out using javascript or is it possible to pass javascript variables to a server side language like PHP.
for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...
I would like to display the number 1 at first and then 2. but this code produces number 2 for both alerts. I was able to achieve what i wanted with "new" constructor when creating functions but this is not a good practice and after all i am passing these functions as an event handlers and it can't be done with "new" keyword because it is throwing error. I think there are some solutions with arrays e.g the x would be an array of numbers, but i don't like it. Am i missing something important?
I use onclicks to bring up a hidden DIV as a dialog box that blacks the background out, can I use this same line of code and pass in variables or should I create a box for each item?
I am new to jquery. The project reuirements specify using jquery and java scripting. I have several web pages that set variables. I need to access these variables on another page.
What is the best way of doing this? Can yoy give me an example?
On the response to my first post, "Passing Variables", I see how to use the cookies. How would I use session variables? I thought you could not access them via jquery.
Alright, I'm trying to make these variables pass through as a post, but it's not receiving any posts through the other side. When I use the GET method though, it picks it up.
I'm using AJAX to, on the click of a button, run a PHP script that dynamically generates a new line of text, and passes that to the script.The PHP script, new_sentence.php, just echos out the sentence.This works fine.But what I would like to do is for the PHP script to dynamically change JavaScript variables.how to pass multiple variables from PHP to JS.I can, of course, pass one by having the PHP script echo anything, and then use JS to set the variable to the PHP output. But what if I wanted to set two or three JavaScript variables at once?Here's my code in the HTML page that contacts new_sentence.php:
Code: function ajaxRefresh(){ var ajaxRefresh; ajaxRequest = new XMLHttpRequest();[code].....
When I press the "Refresh" button on the HTML page, it runs the ajaxRefresh function, which calls new_sentence.php. Then, once it gets the response, it changes the text of the element named "div" to whatever text the new_sentence.php echos.I'd like to figure out how to get a couple of variables.I would imagine this is simple. how to set the variables in PHP and then how to retrieve them in JS.
i need to pass variables to a popup page. I have already made the page i want to be popped up, it is called popup.html and is in the same file location.Here is how i am making the page popup:
<head> <script type="text/javascript"> function prizes(){
I have a form with allot of form items on it that posts to itself. I am trying to pass those form values to another page with out using the action attribute in the form. Is there a way to do this? I have tried jquery and javascript but coming up blank. Just trying to pass all the values at one time to another page. Seems a little difficult to me since im a intermediate javascript programmer. Here is what i am trying to do script wise. theform is the ID of the form. I have a switch statement that is based on the button pressed would get into that statement. So if one of the three buttons on the page is "excel report" it should get into that statement and pass the values of the form to another page. I have tried this:
Now i have a doubt, how i can pass the variables $var and $var1 with ajax to a PHP file? to make sql querys and replace the values of $var and $var1[code]...
