JavaScript - Add By A Percentage Rather Than A Number

Hi. Can someone please tell me if a bent percentage silder is possible (something like this http://www.codingforums.com/showthread.php?t=173255 only I want it to be bent about 330 degrees, and I wouldn't want to link to another class-I would like to host the entire code on my website)? Also, the reason I want the slider to be bent, is because I would like the slider to be a sort of bent rectangle, and when the user clicks/drags the slider, the rectangle would "fill" to that point (change its background color up to where the mouse is). Thank you. Bye.

I am trying to create a function or have this work some how where it displays the first number when you make your choice in the first drop down box, which is working so far. In the second drop down box, if any of the answers are chosen except for none, it will take off 10% of the first number. Then add or subtract from there. I just have a problem with creating a function to take off that 10%. Here is the javascript:

I have my cumulative totals box at the very end of my order form and I'm required to have another underneath that one that will give a particular discount depending on how great the total of the order is.

Would someone please be able to give me the javascript codes that will allow me to do this and also tell me where I'm to put them.

Is there a way with Firefox/Chrome to get the actual % used instead of the rendered pixel values?

For example I have a table with the following CSS markup
Code:

#tableFoo : { width : 50%; }

In IE to get the percentage set in the CSS file, it is as simple as:

Code:

var width = tableObj.currentStyle["width"]

I am having trouble figuring out a way to get the percentage value with Firefox and Chrome. I am thinking it is not possible other than stylesheet sniffing and ripping out the rules that way which I am not going to do.

Thanks,
Eric

Hi,

I am fairly new to this so please bare with me.

I have a php page that uses Javascript (I think) to calculate the percentage Insurance Premium Tax (IPT field) of a total.

I have located where the calculation occurs and can see that it take the total of a predefined amount and divides it by 21 to give me the 5% IPT tax. IPT has risen in the UK today to 6% so I need to know what I need to change the 21 to to give me an accurate IPT calculation.

Here's a snippet of the code. Can anyone help please? Is it 17.65?

PHP Code:
////////////////////////////////////////////

$p = 3;
$q = 0;
  while ($p < 6){
  $base_array = mysql_fetch_row($result4);
  // Motor Bikes
  $risk_code = 2;
  $ap = (0 + ($p));

          $ipt_rate = $ipt_main;

  $monthly_total = $pricing_row[$ap];
  // Calculate IPT
  $ipt_percentage = $monthly_total / 21;
  $monthly_ipt = $ipt_percentage;

    $base_cost = $base_array[0] + $dealer_loading;
  $base_final = $base_cost;

I am trying to customize this scrollbar so that it will fit all screen resolutions and I was wondering how I could do this by somehow customizing the JavaScript files created by Nathan Faubion or if I could do this using other JavaScript variables (var widthPercentage) to change the pixels to percentages? Please let me know what you think. Thank you very much!

One of the pages on the website I'm using the JavaScript on: http://www.clintshipley.com/about.html

Code:

JavaScript file jsScroller.js:
//Created by Nathan Faubion http://www.n-son.com/scripts/jsScrolling/
function jsScroller (o, w, h) {
	var self = this;
	var list = o.getElementsByTagName("div");
	for (var i = 0; i < list.length; i++) {
		if (list[i].className.indexOf("scroller-content") > -1) {
			o = list[i];
		}
	}
	
	//Private methods
	this._setPos = function (x, y) {
		if (x < this.viewableWidth - this.totalWidth) 
			x = this.viewableWidth - this.totalWidth;
		if (x > 0) x = 0;
		if (y < this.viewableHeight - this.totalHeight) 
			y = this.viewableHeight - this.totalHeight;
		if (y > 0) y = 0;
		this._x = x;
		this._y = y;
		with (o.style) {
			left = this._x +"px";
			top  = this._y +"px";
		}
	};
	
	//Public Methods
	this.reset = function () {
		this.content = o;
		this.totalHeight = o.offsetHeight;
		this.totalWidth	 = o.offsetWidth;
		this._x = 0;
		this._y = 0;
		with (o.style) {
			left = "0px";
			top  = "0px";
		}
	};
	this.scrollBy = function (x, y) {
		this._setPos(this._x + x, this._y + y);
	};
	this.scrollTo = function (x, y) {
		this._setPos(-x, -y);
	};
	this.stopScroll = function () {
		if (this.scrollTimer) window.clearInterval(this.scrollTimer);
	};
	this.startScroll = function (x, y) {
		this.stopScroll();
		this.scrollTimer = window.setInterval(
			function(){ self.scrollBy(x, y); }, 40
		);
	};
	this.swapContent = function (c, w, h) {
		o = c;
		var list = o.getElementsByTagName("div");
		for (var i = 0; i < list.length; i++) {
			if (list[i].className.indexOf("scroller-content") > -1) {
				o = list[i];
			}
		}
		if (w) this.viewableWidth  = w;
		if (h) this.viewableHeight = h;
		this.reset();
	};
	
	//variables
	this.content = o;
	this.viewableWidth  = w;
	this.viewableHeight = h;
	this.totalWidth	 = o.offsetWidth;
	this.totalHeight = o.offsetHeight;
	this.scrollTimer = null;
	this.reset();
};

How can i "prompt the user for the sales tax rate as a percentage"?
Thanks soooo much for any help!

this is what i have so far....

var tax = prompt("What is your tax rate percentage?", "")
document.write("Return Value: "+tax,("<br />"));

I am having issues with my code... below are the instructions.

"prompt the user for the cost of a purchase and the sales tax rate as a percentage. Calculate the tax amount and the total cost. Display all 4 values in the document"

I am having some real issues with the tax rate percentage, it keeps showing as a decimal, and does not calculate correctly. Any help is highly appreciated. Thanks so much!




var cost = prompt("What is the cost of your purchase?", "")
document.write("Return Value: "+cost,("<br />"));

var tax = prompt("What is your tax rate percentage?", "")
document.write("Return Value: "+tax,("<br />"));

var salestax= cost * tax
document.write("Return Value: "+salestax,("<br />"));

var total = eval(cost) + salestax
document.write(total, ("<br />"));

Hi. Sort of new to Javascript.

I am implementing a zoom in feature, but actually tricking the user as a full screen image is simply being stretched.

I plan to apply it to several pages, and don't really fancy working out the pixels for each.

I believe that if you simply put width: 150% height 150% it will change the image size relative to the browser. I don't want that, I want it relative to the original image size. Could I do sort of height*1.5 or something? How would I write that if so? Thanks!

Code:

<script>

$('#in').click(function() {
  $('#drag img').animate({
    width: '150%',
	height: '150%',
  }, 5000, function() {
    // Animation complete.
  });
}); 
</script>

I am delving into the coding world and while I understand the basic principle of cookies, conditional statements, arrays, etc... I am still learning how to properly implement them. Any asistance with the following situation would be greatly appreciated and help with my learning as I try to reverse engineer the logic. I have looked around the web and this forum with little success. If the situation below is too complicated, I would really appreciate even a shove in the right direction regarding the logic.

-----------------
How could I show a preset counter which counts up from a preset, beginning number toward a preset, end number? I imagine the increment and speed is set be the difference between the two numbers and a timeframe.

Assumptions:
I would rather not set the increment but edit the end number to show a steady increase. As I update that number, the increment adapts dynamically.

I would want the number/script to be useful, so it should not refresh to the beginning number on each page load (i.e. num=0). When a visitor comes to the page, it must seem like the counter has been steadily been increasing in their absence.

Coke or Pesi did something similar one time regarding cans sold to date (doubt it was plugged into a DB somewhere but rather based on a steady sales figure) and it was pretty cool.

All the best!

Ooook so this is probably the stupidest question ever. I know in java you can take advantage of a number being an int (not double) and divide by something without getting a remainder. But in javascript you dont declare what kind of variable something is.

So my problem is: Given any double or triple digit number, how do i get all but the last digit. Like if i have 13, I need to make an int with 1. If it's 103 i need one with 10.

Thanks!!

Hi All,

Im a total novice with coding other than html/css.

I have a video xml which, in which i need a new feature, could you help me with that?

Basically my video is being entered with a time of it - for example 30sec.

I have start and end trackers firing for the video but now i want to add impression trackers at 25%, 50%, 75%. I managed to do it using specifying seconds for the calls, but it becomes a pain to recalculate seconds for every video.

Any ideas I could follow?

Thanks,
AD

I can generate a random number between 1 and 9,
( var rand_no = Math.floor( 1 + Math.random() * 9 ); )
but I want to add that random number to a value that is enterred into an inputbox and get a total.
How can I do this using Javascript and put the result into a hidden field.
I will also need to use that same random number in another place on another form .

Thanks

Hello,

I need to be able to get a number to 2dp without rounding e.g.

14.756 needs to be 14.75

I tried .toFixed(2) but this rounds.

I thought of converting to a string and performing string functions but it seems like over kill if there is an easier way.

thanks
