This pages calls a function on a separate php page to run 2 mySQL queries, the value must be put in the text 3 times in quick succession before the database is altered. I've tried all the other functions and they seem to be fine, AJAX is my weakness but I need it for the main functionality of my website. I need this to work.
I have a self project I am exploring. I would like to play a simple sound file each time a function is run. The function runs every second, so, basically, I am just trying to get an audible click sound file to run every time the function runs. I do not know how to play a sound file thru javascript. Here is the code file thus far...
i've got a program that gets input from a user, and then stores it in a cookie. That bit is fine, what is a problem is that its just overwriting the data each time a new entry is made, i believed this to be something do do with it not being numbered entry's, so i added a number into the entry, but for some reason it wont add 1 to the number variable each time the function is called
I have 2 things going on here. One, the 'percent' variable is constantly showing up as NaN (not a number) no matter what numbers I give it. I suspect it is happening because the function is populating all the fields at one, which causes a 'divide by zero' scenario for the percentage field, which is last in line. Which brings me to my send thing. How to write this function correctly, as it obviously is causing problems as is, and it seems clunky. I think it should broken up into a couple different functions, but I tried that and NOTHING worked.
Here is the code, let me kow what you think: function calculate(){ var contractsAdded = document.forms[0].contractsAdded.value; var priceAdded = document.forms[0].priceAdded.value; var contractsSold = document.forms[0].contractsSold.value; var priceSold = document.forms[0].priceSold.value; var totalAdded = (contractsAdded * priceAdded) * 100; var totalSold = (contractsSold * priceSold) * 100; var gainLoss = totalSold - totalAdded; var percent = gainLoss / totalAdded;
I have a function which is called twice. It allows the elements of an array to be set to a different color, successively:
function ln8 (arrayA,color,current) { var arrayB=(typeof arrayA == 'string')? arrayA.split(',') : arrayA; var line = document.getElementById(arrayB[current]);
question: if you want a link which simply runs a js function is it acceptable to have no href? the problem with this is the cursor doesnt change when you hover over, but if you put # as the href it jumps to the top of the screen which is sometimes unacceptable. what it the best solution to this? granted you could do event handling behind the scenes and just intercept the clicks and prevent the href from going anywhere, but sometimes you just want to stick an onclick on the anchor tag!
Problem in the timing of the script. The problem is that when I try to get an id of an object that was added by ajax, the script doesn't recognize it. The html: <select id="categories" name="categories"> <option value="3">aa</option> <option value="43">bbb</option> </select>
When I load the page, there is this script that get the value of the #categories and use ajax to fill another select and in the same ajax, I load images by another function using the new select input that was created: function fill_subcategories(){ parent=$("#categories").val(); $.ajax({ type: "post", url: "ajax/sub_galleries.php", data: 'parent='+parent, success: function(data){ $('#sub_categories').html(data); }}); show_exist_imgs() }
This fills this div: <select name="sub_categories" id="sub_categories"></select> Right after filling the #sub_categories, I use another ajax that get images of the new id of the #sub_categories, and here I get the problem.. the js: function show_exist_imgs(){ g_id=$('#sub_categories').val(); $.ajax({ type: "post", url: "ajax/show_exist_imgs.php", data: 'g_id='+g_id, success: function(data){ $('#exist_files').html(data); }}); } This script doesn't recognize the id of the new $('#sub_categories') select input.. why is that?
I have created some code that alerts me the contents of all the child divs inside a main div
function CheckEventLayout(){ //check all divs in area and resize overlapping divs var RunOnce; if( RunOnce != true ){ var StartTimes = new Array(); var EndTimes = new Array(); var i = 0; $("div#day-view-overlay").children("div.day-view-appointment").each(function(){ var DoOnce; if( DoOnce != true ){ alert($(this).html()); ..... CheckEventLayout();
The problem is this code is on a page that is loaded via post and if you go off the page and then back onto it jquery seems to attach the function again so it runs twice. So need to unbind this function before the script runs again.
If this search function is included in an include file with other functions it will run more than once if you click another function first, then come back to it to do another search.
For example if I click the next page function, then decide to click for a new search it runs more than once: Next page function:
Code: $(document).ready(function() { $('a#nextpage').click(function() { var page = $(this).attr('page'); var searchval = $(this).attr('schval'); var maxpage = $(this).attr('maxpage'); $.post("findowner.php", { p1 : searchval, page : page }, function(data){ if (data.length>0){ $("#ownerIDdiv2").html(data); } }); }); }); //end
However, if I put the first search function in a separate include file all works perfect. Why it runs multiple times if it is grouped among other functions?
I've got an array of names, and one ID. I need to run an ajax call using the ID and each lastname, until I get a successful hit on the ajax call. I can't quite figure out how to determine if the function that runs the ajax call has succeeded or not, it always returns false for me... Here's the code for the loop:
I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below
window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.
I'm trying to make a time script for an app I'm making (this is not an HTML document; it's a .js file to be used with Titanium) however I'm having trouble getting the function to display and update.
function updateClock() { setInterval ( 'kiTime()', 1000 ); } function kiTime () { //Get current date and time [Code]...
If I use kiTime() under the text field I will get the current time (or at least the time the app was opened), however if I call updateClock() it's blank.
When the JS file is not working at the time of Ajax files is called. on first time the onmouseover JS is working but , if you call the ajax JS is not working.
calling a php page through AJAX. and it works Aok. I wanted the ajax backend php file to call a function in the front end page. even a simple alert from the backend php file wont work.
My code to call the alert and parent's javascript functions are below.
Simple alert
echo "<script language='javascript'>alert('Please Help Me');</script>";
I have the following calculation (simplified to focus on the point):
Code: var scroll_percentage = scroll_button_distance/scroll_wrapper_width; or imagine this is:
Code: var scroll_percentage = 100/500; The answer is -INFINITY
How do I make this into a usable number?I searched for INFINITY and found plenty of info but am not sure how to simply get the "0.2" answer I need for the next calculations.
I have a function that sends some data to a PHP file for processing, and call a page refresh after that, but it's not working. This is what I have so far:
function Reload() {location.reload() ;} function del(v,m,f){ $.post("system/reject.php", {id: v}) ; javascript:parent.mainFrame.document.location.reload(); }
The function Reload is something else I tried while trying to get it to work but everything I have done so far doesn't work. :(
I want to run a function only if it has been called from lets say another function, is there an event handler for that? I dont want to call the function on document.ready since it will load without being called?
for example, the below function is run when page loads, how do I just run it only when I call it directly, say from another function..
I've come across functions like the one below in many scripts.I just don't understand the purpose of the parameter! Nothing is being passed into the function when it's being called- so what's the point of specifying an argument???
function doSomething(e) { if (!e) var e = window.event; alert(e.type);[code].....
I'm trying to run this script on Firefox. I'm copying and pasting the whole thing in here just to be safe, but I'm mostly concerned with getting the findLegendary function to call catchPok(). The script executes fine, goes into the battle, but then...does nothing.It runs the catchPok function if I manually click and deselect the "Find Legendary" window option, so alternately, if somebody knows how to make the program automatically click the element at that point to stop repeating the function (maybe?) and it works, I'd be just as happy with that. My best guess is that the autoContinue function might be interfering somehow, since it runs that portion of the code with the manual findLegendary shutoff, but to be honest I'm pretty clueless.
What I want it to do is run the catch function through, catch the game pixel, and then go back to repeating. I don't care how this is accomplished as long as it can feasibly loop. The game rules allow botting, so this isn't against any site rules, either.
what I would like to know is - within the highlight function what ways are there of getting the id of the image element that called the function? I was thinking I could declaritively pass the id to the function like so - onmouseover="highlight(1)". or would onmouseover="highlight(this.ID)" work? Or is there a better way of getting the id of the calling img element from within the highlight function, I'm thinking that perhaps there is a sender object that I can make use of that I don't know about, if so how do I use it?
I stumbled over a strange behaviour of Mozilla. When I want to access the caller property of a function that was not called from within another function, Mozilla seems to abort the script. No error message, no hang, just stopping script execution at that point. Why? And what is the remedy?
I have some javascript the works in conjunction with a flash video player. When a user selects a video in the Flash video list and new video is called and begins to play. Also, when that video is selected a function called "doOnMediaLoad()" is called and inside of that function I have put a call to another function that I wrote in the same script.function that is called when user selects flash player video list.
function doOnMediaLoad(e) { vcomments_changed(e.id); //call to my function }

I am making a small gallery script. When a user clicks an image, I would like for a function to be called that tells the browser where that image is located in an object. For example:

It works, I just don't like it because it is messy and it seems sensible that some workaround exists.
