JavaScript - Multiple Functions Need Help

Similar TutorialsHi, i have got this piece of code: Code: var f = [];
var x = 1;
f[0] = function(){alert(x);};
var x = 2;
f[1] = function(){alert(x);};
f[0]();
f[1]();
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 want with "new" constructor when creating functions but this is not a good practice and after all i am passing these functions as an event handler and it cant 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? Thanks for your replies. Hello, so I'm trying to call multiple functions with onClick. It doesnt really work, just wondering why. Advice or tips would be nice, thank you guys for your time.

After a lot of help from you guys I have tackled my RSS feed issue (sort of) to the point where i have a page that does basically what I need it to (http://www.the-rational-investor.com/test042311.php/). I now need to incorporate this java script developed into the big picture and of course, there seems to be problems. Since I know it works on its own, I must be running into problems getting all the functions working simultaneously and I once again need to call on the board's brilliance in figuring out what I am doing wrong....so here it goes I have taken out a lot of unnecessary code just to focus on the java script.

Thanks again for all your wonderful help and all the best to you and your families on this Easter weekend, Brian Ok, so basically what I've got is a button which when clicked, "opens" a section of the page. I also need the button to "jump" to this section of the page, because it's below the current content and won't be visible. What I've got so far is ... Javascript <script language="javascript"> function toggle() { var ele = document.getElementById("toggleText"); var text = document.getElementById("displayText"); if(ele.style.display == "block") { ele.style.display = "none"; text.innerHTML = "show"; } else { ele.style.display = "block"; text.innerHTML = "hide"; location="#ordernow" } } function moveWindow(){window.location.hash="ordernow"} </script> HTML ... (The rest of the form is up here) <input name="Button" type="button" class="button" value="Order Now" onclick="toggle();moveWindow()" id="displayText"/> ... (This is the start of the section that becomes visible, along with the anchor point which is highlighted in red.) <div id="toggleText" style="display: none"> <a name="ordernow"></a> <fieldset> <legend>Order Confirmation</legend> <div class="standardinput"> <label>Company:</label> <input name="Company" type="text" class="textinput" id="Company" /> </div> If I put two separate buttons, both functions will work. Basically I need them to be on the same function, not sure how to do that? Thanks so much in advance =) I am having trouble running multiple windows.onload functions and having trouble how to implement them. I found a couple articles on but couldn't really get them to work. Here are the two functions I'm trying to load: Code: <script type="text/javascript">
//<![CDATA[
window.onload=function(){
//randomize order of contents with DIV class="group1"
randomizeContent("group1")
randomizeContent("group2")
randomizeContent("group3")
}
//]]>
</script>
Code: <script type="text/javascript">
function showHideMore(obj) {
var contObj = obj.parentNode.getElementsByTagName('div')[0];
var status = (contObj.style.display == 'block')? 'none' : 'block'
contObj.style.display = status;
<!-- obj.innerHTML = (status == 'block')? 'Show less' : 'Show more'; -->
obj.curPic = (obj.curPic == 0)? 1 : 0;
obj.style.backgroundImage = 'url("'+plusMinusPics[obj.curPic]+'")';
}
window.onload=function(){
plusMinusPics = ['plus.png','minus.png'];
oMoreLessSpans = document.getElementById('list1').getElementsByTagName('span');
for(i=0; i < oMoreLessSpans.length; i++){
oMoreLessSpans[i].curPic = 0;
oMoreLessSpans[i].style.background = 'url("'+plusMinusPics[oMoreLessSpans[i].curPic]+'") no-repeat 0 50%';
oMoreLessSpans[i].onclick=function(){showHideMore(this);}
}
}
</script>
I posted a thread a few days ago concerning a bit of javascript code to make checking one checkbox clear another one. I got some great, prompt help. However, I just got back to working on that web page, and realized that the functions only work on the first form on my web page. I have many forms and they are actively named using php. Here's are the functions (these works for just the first form on the page): Code: <script type="text/javascript">
function undo_Changes() {
if (document.getElementById("Complete").checked==true) {
document.getElementById("Needs_Change").checked=false;
}
}
function undo_Complete() {
if (document.getElementById("Needs_Change").checked==true) {
document.getElementById("Complete").checked=false;
}
}
</script>
I call them from the checkboxes involved: Code: <input name="Complete" id="Complete" value="Yes" <?php echo($Complete=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onChange="this.style.color='#FF0000'" onClick="undo_Changes()"> <input name="Needs_Change" id="Needs_Change" value="Yes" <?php echo($Needs_Change=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onClick="undo_Complete()"> Here's how my forms are named: Code: <?php $DocName = "Schedule".$count; ?>
<form name="<?php echo $DocName; ?>" action="ScheduleCode.php" method="post" id="<?php echo $DocName; ?>">
I've tried the following and it doesn't work at all: Code: <script type="text/javascript">
function undo_Changes(myForm) {
if (myForm.getElementById("Complete").checked==true) {
myForm.getElementById("Needs_Change").checked=false;
}
}
function undo_Complete(myForm) {
if (myForm.getElementById("Needs_Change").checked==true) {
myForm.getElementById("Complete").checked=false;
}
}
</script>
<input name="Complete" id="Complete" value="Yes" <?php echo($Complete=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onChange="this.style.color='#FF0000'" onClick="undo_Changes(this.form)">
<input name="Needs_Change" id="Needs_Change" value="Yes" <?php echo($Needs_Change=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onClick="undo_Complete(this.form)">
Thanks for any help. Lisa Every time I try to use the notEmpty function with an onClick event, the validation stops working. I also need to implement a pop-up that gives me this information - alert("Your name is"+firstname +lastname", your G.P.A. is "+gpa "your phone number is "+phone); anytime I try to use it as a function with onClick, it interrupts the validation as well.

Hello, Ok so the following code works. Code: function myFunction(myName)
{
alert("You are "+myName);
}
callFunction = "myFunction";
parameter = "Joe";
window[callFunction](parameter);
However this code doesn't work: Code: function myFunction(myName, myAge)
{
alert("You are "+myName+" and "+myAge+" years old.");
}
callFunction = "myFunction";
parameter = "Bill,15";
parameter = parameter.split(",");
window[callFunction](parameter);
The above code alerts: "You are Bill,15 and undefined years old." Thanks for the help! Hi, I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing. Can anyone see what I'm doing wrong? Code: function testWrapper()
{
function frequencyWrapperOne()
{
var numberArrayOne = new Array(0,0,0);
for (var i = 0; i < 1000; i = i + 1)
{
var chosenNumber = Math.floor(Math.random() * 3);
if (chosenNumber == 0)
{
numberArrayOne[0] = numberArrayOne[0] + 1;
}
if (chosenNumber == 1)
{
numberArrayOne[1] = numberArrayOne[1] + 1;
}
if (chosenNumber == 2)
{
numberArrayOne[2] = numberArrayOne[2] + 1;
}
}
return window.alert(numberArrayOne.join(','));
}
}
testWrapper();
Thanks. Ok here is what I have so far, my ending part of my Call Function I think is ok. for my main function. I think I misplaced the { and } I will show you all the codes I have for my main function this is what I have I think I did misplace something but I can not pin point where that one small things should be Code: unction showResults(race,name,party,votes)
{ // script element to display the results of a particular race
var totalV = totalVotes(votes);
document.write("<h2>" + race + "</h2>");
document.write("<table cellspacing='0'>");
document.write("<tr>");
document.write("<th>Candidate</th>");
document.write("<th class ='num'>Votes</th>");
document.write("<th class='num'>%</th>");
document.write("</tr>");
}
for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("td class='num'>" + votes[i] + "</td>");
var percent=calcPercent(votes[i], totalV)
document.write("<td class='num'>(" + percent +"%)</td>");
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}
</script>
Just wondering if i misplaced any ; or { or } anywhere suggestions? Here is my call function Code: <script type="text/javascript"> showResults(race[0],name1,party1,votes1); showResults(race[1],name2,party2,votes2); showResults(race[2],name3,party3,votes3); showResults(race[3],name4,party4,votes4); showResults(race[4],name5,party5,votes5); </script> I been going over this, I can not seem to figure out what { i might be missing? Thanks Is there a way to activate a function from another function? It has to be in the script tag, it can't be in the HTML section. Can I use something similar to this following code? If not, can anyone give me some help? I have tried to do it various ways, and have looked it up a few times, but to no avail. Can I use something similar to this following code? If not, can anyone give me some help? if (condition) {activate functionname();} Any help I can get would be appreciated. Thanks a lot to anyone who can help. Hi, I hope someone can help me. I'll be honest and say I don't know much about javascript, but am fairly comfortable in html. I am building a website that will have multiple image swaps on multiple pages. I am building this in wordpress, and I'm guessing that means my approach will be different than if I wasn't using wordpress. Here's how one page would work: There are 10 images shown. 1,2,3,4,5,6,7,8,9,10. When number 1 is clicked on, I want a new image - 1a. When 2 is clicked on, 2a. So there are 20 different images in all on a given page. Also, I want the user to be able to click on the image again to restore the original image. I would prefer onclick to onmouseover. There will be literally dozens of pages like this on the site, managed by wordpress, so hundreds of images to swap. Basically the first image is a question - the second image is the answer. Is this possible? im no jQuery rookie but for the first time ...instead of simply writing out the animation jQuery('element').hide() in that way.... i instead needed to keep track of the functions so i wrote it like function hidetheElement() { jQuery('element').hide() } but now i need to run 2 of those functions together after a click ...for example jQuery('ClickedElement').click( movethelement,hidethelement ) see what i mean?....i dont know how to properly run two defined functions whats the proper syntax.... and here is my actual code for reference (its basically a menu link being clicked...hiding one page...and showing another....i needed to define the functions so if a menu link is clicked it could hide every other page first...by function....and then call a function to show the page Code: jQuery(document).ready( function() {
jQuery('#ladiesmenu').click(
previewoff,ladieson
);
function previewoff() {
jQuery('#preview').fadeOut(500);
}
function ladieson() {
jQuery('#ladies').fadeIn(500);
}
Code: <html>
<head>
<script>
//declare variable
//var temp = 0;
var Num = parseInt(prompt('Enter an Intger'));
// starts the function factorial
factorial(Num);
//The function is declared
function factorial(currentNumber) {
if(currentNumber > 1) {
//temp = temp + (currentNumber);
factorial(currentNumber - 1);
alert(currentNumber);
}
else {
alert("here");
}
}
</script>

This code is suppose to take the prompt number and keep subtracting one if > 1 but it seems to be not doing that at all and doing the else statement first then + till it gets to the prompt number. I have been staring at it for a while now and cant work it out. Thanks I need to input the functions for the buttons ( Push, Pop,Peek, Enqueue, and Dequeue) nothing I try works. Can anyone possible help me with one of the push, pop or peek, and then one of the Enqueue or Dequeue (any information I see online always has to do with wordpress which im not using) . Im really not asking for someone to do all the work for me, I just need a start. ok here is my code with the buttons just no functions <html> <head> <title>COP2500 - Lab 9</title> </style></head> <body> <center> <h3><b>COP2500 Assignment 9</b></h3> <b>Queue:</b> <form name="queue"> <input type=text size=60 name="display"><br> <input type=text size=5 name="entry"> <input type=button value="Enqueue" onClick="enqueue()"> <input type=button value="Dequeue" onClick="dequeue()"> </form> <hr> <b>Stack:</b> <form name="stack"> <table> <tr> <td>Entry: <input type=text size=5 name="entry"><br> <input type=button value="Push" onClick="push()"><br> <input type=button value="Pop" onClick="pop()"> <br> <input type=button value="Peek" onClick="peek()"><br> </td> <td><textarea name=display rows=20></textarea></td> </tr> </table> </form> </center> <script language="JavaScript"> var myqueue = new Array(); var front; var back; front = 0; back = -1; var mystack = new Array(); var top; top = -1; function enqueue() { // This function should take the value from the 'entry' text box and // add it to the back of the queue. The 'back' queue variable must be // incremented. // Since the queue changed, call the display function. Done. display_queue(); } function dequeue() { // This function should display the value of the 'front' element // in the queue using the 'alert' function and then increment the value // of the front variable. // if the queue is empty, i need to say so. // Since the queue changed, call the display function. Done. display_queue(); } function push() { // This function should add the value in the 'entry' text box to the stack, // and then increment the value of the 'top' variable. // Since the stack changed, call the display function. . display_stack(); } function pop() { // This function should use the alert function to display the top // of the stack and then remove the top item from the stack. // You can 'remove' the item simply by decrementing the value of 'top'. // If the stack is empty, it needs to say so. // Since the stack changed, call the display function. . display_stack(); } function peek() { // This function should use the 'alert' function to display the top // of the stack but not change the stack. If stack is empty,it needs to say so. } // ***************************************************************** // Do not edit anything below this line. Use the functions as given. // ***************************************************************** function display_queue() { var output; var i; output = " "; for (i = back; i >= front; i--) output = output + myqueue[i] + " "; document.queue.display.value = output; } function display_stack() { var output; var i; output=""; for (i = top; i > -1; i--) output = output + mystack[i] + "\n"; document.stack.display.value = output; } </script> </body> </html> . Why do we have functions without parentheses at times? Ex 1) http://www.youtube.com/watch?v=OHYFNDzlDTE (On 2:18) Ex 2) At the bottom: Code: var panel, flag;
function mousemoveResponse(e)
{
var x, y;
if( window.event )
{
x= event.x; y=event.y;
}
else if(e)
{
x=e.pageX; y=e.pageY;
}
if(flag)
{
panel.innerHTML = "Mouse is at X: " + x + ", Y: " + y ;
}
}
function mouseoverResponse()
{
flag = false;
panel.innerHTML = "Mouse is Over";
}
function mouseoutResponse()
{
flag = true ;
}
function init()
{
panel=document.getElementById("panel");
flag = true;
panel.innerHTML="Move the mouse..." ;
document.onmousemove=mousemoveResponse;
panel.onmouseover=mouseoverResponse;
panel.onmouseout=mouseoutResponse;
}
onload=init;
Hi, I am creating a mashUp with google maps and have a function that creates the map, marker, infowindow and all works great. I want to add more functions to that functions file. Do I start with another function Name() put my function in the {} and then I am going to use the onclick event when I want the function to run. I also am going to add more functions to this file Is that the correct way to keep adding functions? And what is the best way of calling them in my html file? Answers and examples would be great thank you I'm a newbie student coder for now, hoping to enter the wonderful world of software engineering in another year. I put together a very simple site for a class and all is well, but my "Contact SRS" form doesn't seem to want to run my JavaScript code even though I've used a JS debugger which returned no errors. When I click the Submit button it's supposed to validate the form. But I keep getting "Error on page" in the bottom IE 7 message bar (where it usually says "Done" when you load a page). There is another function that also does not work - it's in the Telephone number fields - it' supposed to check that the values entered are numbers. Would anyone be kind enough to try to run this page in your browser and see if the validation functions runs for you? If they don't, could you offer any suggestions as to code errors or possible browser settings that might be causing the problem? Thanks in advance to anyone offering their time!!!
