JavaScript - Simple Syntax Question
I have an alert I'm using over in Salesforce to remind sales reps to use a special terms document when quoting.
Problem is, the alert is going off for ALL accounts, not just "Account1" and "Account2". Is this line incorrect in syntax or something? if ((isstatus == "Proposal/Price Quote") && (acct == "Account1", "Account2")) Thanks all. This forum has been very helpful for me in the past so this was my first stop! Jeremy Code: <html>
<head>
<script type="text/javascript" language="javascript" src="/js/functions.js"></script>
<script type="text/javascript" src="/soap/ajax/10.0/connection.js"></script>
<script type="text/javascript">
function throwalert()
{
var isstatus = "{!Opportunity.StageName}";
var acct = "{!Opportunity.Account}"
var msgg = "Please remember to use a special terms and conditions quote template when quoting this opportunity.";
if ((isstatus == "Proposal/Price Quote") && (acct == "Account1", "Account2"))
{
alert(msgg);
}
else
{
window.parent.location.replace = "{URLFOR($Action.Opportunity.View, Opportunity.Id,null,true)};"
}
}
</script>
</head>
<body onload="throwalert()";>

What does it do and how can we use it? I am studying the javascript. I got following codes from json2.js but do not understand syntax of them. if (!this.JSON) { this.JSON = {}; } (function () { ... }()); For 2nd part, why there is () outsider function? and why these is () after function? Thanks a lot. The following code snippet: (this.inputArray is already defined and initialized prior to this code sequence) if(this.inputArray.length >= 0) { this.inputArray[this.inputArray.length] = new Object(); this.inputArray[this.inputArray.length].type = 'pcDisp'; this.inputArray[this.inputArray.length].data = a; } the first line in the code block should create a new array item and initialize it with the various assigments in the next lines. But Firefox complains "this.inputArray[this.inputArray.length] is not defined". This is very disconcerting because the code has to create array items with different data based on conditionals. So I must be able to automatically create new items as necessary. I thought that javascript had 'late binding', but maybe that doesn't apply here. So, does anyone have a clue for me? My site will change color schemes when a user presses the button in the top left. I want to add a third theme though. I can't figure it out though.

I don't think you need the css's. If, however, I'm wrong just let me know. Keep in mind that the javascript is external. Here's my site if you need a better look Votillity Thank you Hello, In the below script syntax, a simple table converts Celsius degrees into Fahrenheit, using the For loop and integrating it into a table. Code: <html>
<head>
<title>Celsius-Fahrenheit Converter</title>
</head>

<table border=3>
<tr><td>CELSIUS</td><td>FAHRENHEIT</td></tr>

document.write("<tr><td>"+celsius+"</td><td>"+((celsius*9/5)+32)+"</td></tr>");
}
</script>
</table>
</body>
</html>
My questions are about the following script inside the <td> tags: <td>"+celsius+"</td> <td>"+((celsius*9/5)+32)+"</td> 1) why is the script inside the above <td> tags placed between " " ? 2) why is the script inside the above <td> tags placed between + + ?

Hello, I am new to javascript. Below is the code that opens a new window when the user clicks on the button "Click here to see". But the code resides outside the <script></script>. As far as i know javascript codes have to be between these tags to work. How will the "window.open" statement work? Code: <form>
<input type="button" value="Click here to see" onclick="window.open('http://www.yahoo.com')" />
</form>
I want to Count the number of occurrences of character 't' in a string entered by the user (via prompt) and write the result to the web page. For example, if the user enters "Working with strings", you should write a message saying that the string contains 't' 2 times. I know it has something to do with charAt. Im just playing around with it trying to figure it out and got Code: var str = prompt(); document.write(str.charAt(1)); That doesnt count anything up obviously. i need to use a loop but im not sure how to apply a loop and charAt. Ok...this is gonna sound very stupid to you guys, but I don't get one part of this code. Code: function range(upto) {
var result = [];
for (var i = 0; i <= upto; i++)
result[i] = i;
return result;
}
show(range(4));
What does result[i]=i mean? I know it adds the value of i into the array, but how? Why couldn't you just write it as result[i] or result[] = i? I have the following code: Code: if (n==1 && g <=5)
{
sndPlayer1.URL ="Boy-a1.wav";
}
else if (n==1 && g >5)
{
sndPlayer1.URL ="Girl-a1.wav";
}
else if (n==2 && g <=5)
{
sndPlayer1.URL ="Boy-e1.wav";
}
else if (n==2 && g >5)
{
sndPlayer1.URL ="Girl-e1.wav";
}
else if (n==3 && g <=5)
{
sndPlayer1.URL ="Boy-i1.wav";
}
else if (n==3 && g >5)
{
sndPlayer1.URL ="Girl-i1.wav";
}
else if (n==4 && g <=5)
{
sndPlayer1.URL ="Boy-o1.wav";
}
else if (n==4 && g >5)
{
sndPlayer1.URL ="Girl-o1.wav";
}
else if (n==5 && g <=5)
{
sndPlayer1.URL ="Boy-u1.wav";
}
else if (n==5 && g >5)
{
sndPlayer1.URL ="Girl-u1.wav";
}
else if (n==6 && g <=5)
{
sndPlayer1.URL ="Boy-b1.wav";
}
else if (n==6 && g >5)
{
sndPlayer1.URL ="Girl-b1.wav";
}
else if (n==7 && g <=5)
{
sndPlayer1.URL ="Boy-b1.wav";
}
else if (n==7 && g >5)
{
sndPlayer1.URL ="Girl-b1.wav";
}
else if (n==8 && g <=5)
{
sndPlayer1.URL ="Boy-h1.wav";
}
else if (n==8 && g >5)
{
sndPlayer1.URL ="Girl-h1.wav";
}
else if (n==9 && g <=5)
{
sndPlayer1.URL ="Boy-t1.wav";
}
else if (n==9 && g >5)
{
sndPlayer1.URL ="Girl-t1.wav";
}
I was wondering what the best way to make a smaller simpler version of this code is? Would it be using a loop? If so can you help me with how to Code: if(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(emailvalue))
this is a code to validate an email address. My question is.. how do you call this type of validation? Those /^\w+([\.-]?\w+.. i don't really understand how they work. Is there a special term used to describe this? I want to learn how it works. I want to search for tutorials online but i cant think of any desriptive word to use as keyword for google search. I cant find helpful results. Please help.

Hi everyone, I am a newbie Javascript programmer. I have gotten better lately and am starting creating scripts from scratch to test my knowledge. I wrote the script below and needless to say, it does not work... yet. I know I am not far and I need someone's help to tweak my script and let me know what was wrong with. That would be greatly appreciated. Anyone? I have this div in the middle of a page which has an image. I want the image.src to switch to the next image every 3 seconds. Here's my html code: Code: <body> <div id="slideShow"> <img src="pic3.jpg" id="image" /> </div> </body> Here's my js code: Code: window.onload = initLoad;
function initLoad()
{
// Create a new image object
oImage = new Image;
// tie the object image object with your target id in your html code
oImage = document.getElementById("image");
//Create a new date object
var oCurrDate = new Date();
// Create a new time object
var oCurrentTime = oCurrDate.getSeconds();
//Loop through all images in the document
for(var i=0; i<document.images.length; i++)
{
//the current image remains so as long as 3 seconds or less have passed
while(oCurrentTime <= oCurrentTime + 3)
{
// if 3 seconds have not passed, your current picture remains on the screen
oImage.src = document.images[i].src;
}
}
}
I have yet to have my ah-ha moment with Javascript but I think its coming soon. there are small things that seem to be baffling me and Im hoping posting to the forums to get help from people of limitless wisdom. What exactly does the "|" mean in this code? or I should say what does it do? Code: document.template.Aprod_string.value = document.template.Aprod_string.value + "|" + string_recode(Aprod_array) ; I'm building a webpage using javascript and iframes. Basically I have an iframe in the middle of the index.html page that links to another html page (let's call it iframe.html). My question is, is it possible to call a javascript function from iframe.html to control an object on index.html? If so, how do I do this? I'd like to be able to assign an image in iframe.html with the hyperlink of href="javascript:function()", where the function effects the CSS of a div on index.html. Thanks Hi there, a website I am trying to load in an Iframe uses this code to ensure that its window is the top window: Code: <script language="JavaScript"> if (window != top) top.location.href = location.href; </script> I was wondering is there any way possible of loading this page in an iframe or is this method of ensuring the page is on top not beatable? Many thanks, David. |
