JavaScript - Call User Defined Functions With Multiple Parameters
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! Similar TutorialsI need to create a function with named getFontSize() needs one parameter named "id" and id is value of object in document then to create a variable named object to represent object return font size of text in object use style object to retrieve font size and use parseInt() function to get value of font size this is the code i came up with Code: function getFontSize(id) {
// Returns the font size of the object with the value id
var object=document.getElementById(id);
fontsize=parseInt(object.style.fontSize);
return(fontsize);

I have no idea why my functions aren't being recognized by the interpreter as such, but it's probably something simple. Thanks in advance for the help, and I'll be happy to post more code if it might be relevant. I am working on this simple calculator that passes values from one function to another via paramters. I have used alert() to find what is being recieved, so far nothing. here is my code: Code: <html>

function calcArea(l,w) {
var area = l * w
return area
alert("area: " + perimeter) // doesnt work
}
function calcPerim(l,w) {
var perimeter = 2*(l+w)
return perimeter
alert("perimeter: " + perimeter) // doesnt work
}
function calc() {
var width
width = document.calcForm.widthBox.value
var length
length = document.calcForm.lengthBox.value
alert(length + width) // works
calcArea(length, width)
document.clacForm.areaBox.value = area
calcPerim(length, width)
document.clacForm.perimeterBox.value = perimeter
}
</script>

Now, I could write a version of the keypress function for each rectangle, but that seems like poor coding. Can anyone point out how I might restructure the function or the code so that I can pass the number in the onClick to the rectangle it refers to? Thanks I have a good understanding of javascript although I am new to working xml. So I am having a problem getting javascript to recognize that my parameter value in my function call is an attribute in my xml. I called the js function like this: Code: <a href="#" onClick="ebookCategory(marketing);">Marketing</a> Here is my js function: Code: var category;
function ebookCategory(category) {
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","ebook.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName(category);
for (i=0;i<x.length;i++)
{
document.write("<tr><td>");
document.write(x[i].getElementsByTagName("bookCover")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("description")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue);
document.write("</td><td>");
i++;
document.write(x[i].getElementsByTagName("bookCover")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("description")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");
} // end ebookCategory()
Some of the aspects in this function are new to me, xml stuff. Here is my xml setup: Code: <ebook category="marketing"> <bookCover><img src="/millionaire/ebooks/covers/miracle2.jpg" height="150" width="150" /></bookCover> <title>Marketing Miracle</title> </ebook> I appreciate any help in the matter Hey guys, i'm taking on my first minor project in javascript and i've run into an error. For whatever reason, buttons i've defined are calling on functions that supposedly don't exist, yet they are clearly in the code and can be applied anywhere. I also checked the syntax errors in google chrome and they state: Uncaught SyntaxError: Unexpected token else Uncaught reference error: go() is not defined Uncaught reference error: highscore() is not defined. So without further delay, here is the full code. Can anyone help me out? Code: <html>

"%, <br \> Donald's score on the test is " + percentage(donald) + "%");
};
function highscore() {

I'm probably missing something simple here. I have this function called display: function display(name3,office3,officePH3,mobile3,email3) { document.getElementById('viewer').src=('Location_Files/')+(office3)+('.htm') } It's supposed to take 5 values and do various things with them. When I only had one parameter it worked fine, it took an office number which was the value of a listbox option and turned it into a path and then pointed an iframe to that path. Then I changed it so the value of the listbox option was 5 parameters separated by commas. Here's the listbox now: <select onchange="display(this.value)" multiple="multiple" id="People" name="People" style="border-style: none; height:260px; width:220px;"> <option value="test name,1656,phone,NONE,email">Loading</option> </select> You can see display is executed as "display(this.value)" so in theory it should take "test name,1656,phone,NONE,email" as its parameters and it should accept 1656 as the "office3" parameter. For some reason it's not working out that way, the function executes and the iframe changes but I get an unable to display webpage message like the path is broken. Can anyone see what I'm doing wrong? I have added an event listener to a LI item in the DOM: liNode.addEventListener("mouseover", mouseOn, true); The mouseOn function: function mouseOn(e) { // Test for IE or Firefox var e = (!e)?window.event:e; var yPos; if (e.pageY) { yPos = e.pageY; } else { yPos = e.clientY; } } I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this? i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> Hi, This button changes the button text when clicked, but it is always calling the same function.

Each text input will have A or B written in by the user, which should automatically place that letters associated ID in its partner field. If any other letter is entered the ID will automatically be left blank. With the above code I'd need to repeat it over and over for each of the dozens of input fields. The final version wont be using simply A/B either but around 50 possible inputs each with their own ID which would make around 1000 possible variations. What am I missing here that will simplify the process? Thanks Hi, I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it? intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\' I am posting my javascript function he <a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a> function OpenDocPreview(url, docname) { alert('message from search base : ' + url + ' ' + docname); } thank you, Im having problems with this code working as it should. the top banner is supposed to cycle the second banner is supposed to be random the 3rd is a slide show that is supposed to work in order Everything works in random order.

Hi, 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.

hey all, I am now at the point of being able to see the light at the end of the tunnel (woot!). 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. Yes there is PHP code embedded but please don't beat up on me too much for that. here is the main page code: Code: <head>
<?
// function for onmouseover to do ALL THREE tasks //
?>
<script type="text/javascript">
function doChanges(y){
var z= y;
var imagevar = myimages[z];
var imagethis = this.href;
changeimage(imagevar,imagethis);
changetext(z);
var x=y;
var rssfeedvar = myArrayRssFeed[x];
showRSS(rssfeedvar);
}
</script>
<?
// First Task - function for onmouseover TEXT //
?>
<script type="text/javascript">
function changetext(z){
var s= z;
var textchangeEntries = myArrayEntries[s];
var id = document.getElementById("DBtext_large");
id.innerHTML=textchangeEntries;
var textchangeWebadr = myArrayWebadr[s];
var id = document.getElementById("DBtext_link").getElementsByTagName('a')[0];
id.nodeValue=textchangeWebadr;
id.setAttribute('href',textchangeWebadr);
id.innerHTML=textchangeWebadr;
var textchangeEmail = myArrayEmail[s];
var id = document.getElementById("DBtext_email");
id.innerHTML=textchangeEmail;
var textchangeRssUrl = myArrayRssUrl[s];
var id = document.getElementById("DBtext_rssUrl");
id.innerHTML=textchangeRssUrl;
var textchangeRssFeed = myArrayRssFeed[s];
var id = document.getElementById("DBtext_rssFeed");
id.innerHTML=textchangeRssFeed;
}
</script>
<?
// Second Task - functions for onmouseover IMAGES //
?>
<script type="text/javascript">
function changeimage(towhat,url){
if (document.images){
document.images.targetimage.src=towhat.src
gotolink=url
