JavaScript - Keeping Variables Between Functions
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?
Similar TutorialsHi I want help with trying to pass some variables from one function to another. so with the following example: Code:
// main body of script
function exercise() {
fnLLR_Calculate();
fnLLR_Calculate2();
}
function fnLLR_Calculate() {
//-------Gets values from web page------//
var $Shares;
_set($Shares, _getText(_textbox("CALC_STOCK_INPUT")));
$Shares = Number($Shares);
_log("$Shares =" + $Shares);
var $GrantPrice;
_set($GrantPrice, _getText(_textbox("GRANT_PRICE_INPUT")));
$GrantPrice = Number($GrantPrice);
_log("$GrantPrice = " + $GrantPrice);
var $FMVPrice;
_set($FMVPrice, _getText(_textbox("FAIR_MARKET_VALUE")));
$FMVPrice = parseFloat($FMVPrice).toFixed(2);
_log("$FMVPrice = " + $FMVPrice);
var $TaxWitholdRate;
_set($TaxWitholdRate, _getText(_textbox("TAX_WITHHOLDING_RATE")));
$TaxWitholdRate = $TaxWitholdRate / 100;
_log("$TaxWitholdRate = " + $TaxWitholdRate);
}
function fnLLR_Calculate2() {
//----uses values from fucntion 1 to calculate----//
$Result_Shares = ($Shares- $GrantPrice) * $TaxWitholdRate / $FMVPrice;
$Result_Shares = $Result_Shares.toFixed(0);
_log("$Result_Shares = " + $Result_Shares);
}
So i need to pass some variables from function fnLLR_Calculate to fnLLR_Calculate2. What is the best way to do this? Hi everyone, I am working on an assignment and require a little bit of assistance. I have a form (an order form) where I am required to validate the required entries - I have managed to do this with the textbox field no problems. Where I am coming unstuck is with the following items. homePhone - numbers only and max 10 numbers for validation postCode - same as above email validation of @ and . How do I validate comboboxs so that if nothing is selected an alert shows? If the "other address" radiobutton is checked how do I have the text boxes only validate on check? How do I validate the textarea when "do you want a card message" is ticked? I have been working on this for the past week and a bit and have done a fair amount of research and tried to implement various pieces of code I have found with no luck. I have removed some of the select objects to cut down on the amount of code. I am not expecting anyone to write my assignment for me, just wanting assistance to help me learn and become more proficient in JS Regards BP Code: <html>

Hi, Need some help here. To formulate the problem simple i have two buttons with the onclick function: Code: <a href="#" ONCLICK="function1('this')">Click for this!</a>
<a href="#" ONCLICK="function1('that')">Click for that!</a>
When I click this button I actually need to pass the value 'this' or 'that' to function2.. Code: <script language="javascript">
var name = ''
function1(name) {
???
}
function2() {
document.all.textbox.value = name;
}
</script>
I guess what im asking is how can you set a variable by one onclick function and then use it in any other function? Thanks a bunch! Col hi. i know a little php, but new to javascript. much of the syntax is identical. in reading the new rhino book (flanagan 6th), he gives the following example: Code: var square = function(x) {
return x*x;
};
okay, but then he does this: Code: square(plus1(y)) as an example of "invoking two functions in one expresson". (Prior he gives an example of defining a function with plus1, which is how I normally think of functions.) uh, square is a *variable*, but he is using it as a FUNCTION. Can somebody help me understand how this can be? how it works? I'm having trouble conceptualizng how we use a variable as a function. Hi I am using a .js with 3 functions in it 1st function getPeriod is to extract the index of a selected list item 2nd function getRadios is to get the value from a selected radio button 3rd function calculateAmount uses if statments and follows a course depending on which index was selected from the list item in the 1st functino ie . 0,1,or 2 The problem is that the index value is unidentified in the 3rd function when i try to use it in the if statement, but the value of the radio button, the variable "cigs" works... I want to know how to allow the index value to work in the 3rd function I know this is a very silly problem but I cant spend any more time trying to figure it out ...code below ...Thanks ! [code] var index = 0; var element = ""; var cigs = 0; // get the selected item in the list with id listId function getPeriod(listId){ // find the index of the selected item index = document.getElementById(listId).selectedIndex; // use the index to access the text of the selected item element = document.getElementById(listId).options[index].text; // put the favorite into the text field document.getElementById('period').value=index; return index; } function getRadios(what){ // get the cigs value j=what.cigs.length; //alert(j) for (i=0; i<j; i++){ if(what.cigs[i].checked) cigs = what.cigs[i].value } what.buttons.value = (cigs) return cigs; } function calculateAmount (){ if (index = 0) { total = (8.5 * cigs * 182); } else if ( index = 1 ) { total = (8.5 * cigs * 365); } else if (index = 2) { total = (8.5 * cigs * 730); } document.getElementById('total').value=total; } [code] I recently started designing websites, I'm pretty good with working in the design area of expertise. However I am not so great at the development part. I have had little to no experience with java programming. I am putting e commerce on my clients site. He is selling an item that varies in price depending on what size it is. What I am trying to do is have a input for the length and the width and then display the price. I have configured the length and width to multiply and can display the total but I don't know what the if then statement would look like for the price. So lets say the user puts in 4 length and 4 width. I can display 16. But I want to take that and say if =16 then display $21.50 or whatever the cost would be. But I cannot figure out how to code it right for the if then part and then the display part. I am very new to java programming and think i might be a little out of my league with this project but any help you can offer would be great. thank you.
All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero 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 am having some problems keeping the formatting of elements the same for html and javascript, i have a seperate css file for all the formatting of the tags in html, and when i use javascript i want it to stay the same. eg. when i use <h2> Heading </h2> below it wont print the same style as above, the color is the same, but the text is bigger and bold. <script type="text/javascript"> document.write("<h2> Heading </h2>); </script> Any help will be greatly appreciated. Thanks I want to keep the exact same formatting for both, using the Okay, I have this code, Code: <script type="text/javascript">
function changeText2(){
var userInput = document.getElementById('userInput').value;
document.getElementById('boldStuff2').innerHTML = userInput;
}
</script>
<p>Welcome to the site <b id='boldStuff2'>dude</b> </p>
<input type='text' id='userInput' value='Enter Text Here' />
<input type='button' onclick='changeText2()' value='Change Text'/>
A fairly simple one, and it is great, but I want to change it so that the text you type in stays there! Forever! For example, a person visits the site and types in "Hello" then the option of changing the text again disappears, and every visitor after that sees "Hello" (or whatever the first person types). Is this possible? Can anyone help me out! Hi All, I am opening window using following code : Code: <script>window.open('Results.aspx?sorttype=text&sort=OTName&sortname=Document&sortorder=ascending','Results','top=0,left=0,height=715,width=" & sRsultWindowSize & ",toolbar=no,status=yes,resizable=yes,scrollbars=no,location=no')</script>
I want to keep new window top of the parent window. How can i achieve that ? Thanks for your help -John hi, i'm trying to keep a copy of a variable at 4 digits.. this is what i came up with.. it's working but i'm only a noob, so i would very like to know is there any other simpler and/or elegant way to do this.. also i would appreciate it if you could point out any bad syntax or something.. Code:
page = 100
function makeit4digits(){
page4digit = page
if (page<10)
{
page4digit = "000"+ page
}
else if (page<100)
{

}
else if (page<1000)
{
page4digit = "0"+ page
}
}
Beginner here, so please bear with me... Essentially, I'm trying to put together a survey which keeps a running total at the bottom of the page that is updated each time the user makes a choice. So, something like this: Checkbox A - $5.00 Checkbox B - $10.00 Checkbox C - $20.000 Total _____ (Where Total is a textbox.) Originally, I thought this would be easy -- I could just include the onClick attribute in the input tags and call a function each time a checkbox is selected. The problem is that the survey software I'm using doesn't seem to allow me to alter the input tags. Basically, I can create the survey using their customized software and it generates the form, input tags, etc. I can then add customized html/javascript before and after each question. All the code I add appears within the same form. So, is there an easy way to solve this problem without altering the input tags? Hi guy not the greatest with javascript i use it now and then. so far i have this code working correctly. Currently on mouse-over its changes the img background of imgholder. this is the HTML Code: <div id="imgholder">

preload_image_object[i].src = image_url[i];
}
document.getElementById('imgholder') .style.background="transparent url('images/" + imgName + "') no-repeat";
}
currenly if you hover over any of the <a> a css class is applied css code Code: #flash a.grc:hover {
-moz-background-clip:border;
-moz-background-inline-policy:continuous;
-moz-background-origin:padding;
background:transparent url(../../images/animated_nav.gif) no-repeat scroll -148px -59px;
}
what i need to do is keep this class applied over the last <a> that is hovered. so what i would like to do is change the class of the last <a> hover so it stays active until another one is hovered. does this make sense? any help or guidance would be appreciated Hi, I have three buttons on my site. When a button is clicked it pulls down a javascript pop up questionaire box. When the person closes the box they're redirected to Paypal depending on which button they clicked, hence the 3 if else options toward the end of this script. How might the following code be rewritten so that the pop up box no longer exists, but so the options still function and redirect correctly to Paypal? Code: <script type="text/javascript">
function popup(option){
Modalbox.show('<div><p>How did you learn about Dinosaur Pop?</p> <textarea id="message" name="message" rows="4" cols="30"></textarea><br><br><input type="button" value="Send" onclick="Modalbox.hide(); redirect(' + option + ');" /> or <input type="button" value="No, leave it!" onclick="Modalbox.hide(); redirect(' + option + ');" /></div>', {title: "Question", width: 300});
return false;
}
function redirect(option)
{
var messageObj = document.getElementById("message");
if (messageObj != null && messageObj.value != "")
{
var url = 'submit_message.php?message=' + encodeURIComponent(messageObj.value);
new Ajax.Request(url, {
method: 'get',
onSuccess: function(transport) {
}
})
}
if (option == 1)
document._xclick.submit();
else if (option == 2)
document._xclick1.submit();
else if (option == 3)
window.location = "download/Dinosaur Pop Book.pdf";

the .js file in attachments which have somthing that keeps the #usemap from working, would be so thankful if anyone could help thanks This is just a goofy little project to add to my learning, but I've come across a problem that would be nice to solve. It is not a TinyMCE or other JS editor replacement, just something to play with for the holidays! In the following program, you can create an HTML template then add/modify common elements and display the results. I can place tags around highlighted areas and insert/append functions where the cursor is positioned. Works OK so far. The problem is when the text exceeds the <textarea> boundaries and I try to tag or insert at cursor, the display reverts to the first line of the <textarea> display. I would like to keep the displayed area within the boundaries and just push down the inserted text. Problem: Is there a simple way to accomplish this task or do I just have to put-up with the bouncy display whenever I insert code into the area? Code: <html>

One annoyance: When <textarea> content exceeds size of element
additional entries cause display to JUMP to beginning
of the area being edited.

Hello everyone, I have done a lot of research looking for answers on this one but unable to find anything that helps. I have a couple of questions on a page and each are contained in there own form. The questions themselves use checkboxes. I would like the page to not refresh and jump to the top of the page after they submit there answer. So on questions that use radio buttons I have been using Code: <input type="submit" value="Submit" onclick="get_radio_value(); return false;" /> for the submit buttion and that works perfect. I try and use it on questions that use checkboxes and it doesnt work so as a work around I am using the form's action attribute to set it to a link on the page. Here is my form code: Code: <form name="question2" action="#q2">2. <strong>Multiple choice:</strong><a name="q2"></a> Which patient or patients could be transferred to another hospital under the EMTALA Act?<br /> <input type="checkbox" value="a" name="aquestion" />Smith, Bill<br /><input type="checkbox" value="b" name="bquestion" />Wells, Patricia<br /> <input type="checkbox" value="c" name="cquestion" />Hamilton, Larry<br /> <input type="checkbox" value="d" name="dquestion" />Rodriquez, Brad<br /><input type="checkbox" value="e" name="equestion" />Baker, Madison<br /><input type="checkbox" value="f" name="fquestion" />Kahn, Brent<br /> <input type="checkbox" value="g" name="gquestion" />Cahill, Mark<br /><input type="submit" onclick="get_radio2_value()" value="Submit" /></form> <script type="text/javascript" src="first_triage_java_clinical.js"> </script> and here is the javascript code if it helps: Code: function get_radio2_value()
{
var w = 400;
var h = 400;
var wleft = (screen.width/2)-(w/2);
var wtop = (screen.height/2)-(h/2);
