JavaScript - Number/category Association Help Please.
Hey Guys/gasl quick question or see if I could get some help please. When updating our agency's webpage daily, http://opc.deq.state.ms.us/aqi/aqi-msgulfcoastozone.htm I am looking for a shortcut to save time.. When I update air quality numbers. I have to put the conditions. Ex.. 50 = good 100= moderate etc etc. As you see here(bold and underlined)
Code: <table class="output1" style="width: 785px">
<TABLE border=1 cellspacing=0 cellpadding=4 width=550>
<!-- Column headers -->
<TR class='DataColumnHeaderBG'>
<TD align=center>AQI</TD>
<TD align=center>Category</TD>
</TR>
<!-- AQI Values -->
<TR class='Data'>
<TD align=center>44</TD>
<TD align=center class='good'>Good</TD>
</TR>
<TR class='Data'>
</TABLE>
<div id="divAQIHourly">
<p class="mainTitle">
Well instead of having to type good or moderate every-time to correlate with the numbers, I want to find a way the category can automatically default correctly when I put in just the number. Ex, if I put in the number 100, it automatically knows to issue/ put Moderate with out me having to type it. I semi wrote a code .. Yet can't seem to know how to execute. Seeing if Maybe I can get some assistance. Code: <SCRIPT language=JavaScript type=text/javascript>
<table class="output1" style="width: 785px">
<TABLE border=1 cellspacing=0 cellpadding=4 width=550>
<!-- Column headers -->
<TR class='DataColumnHeaderBG'>
<TD align=center>AQI</TD>
<TD align=center>Category</TD>
</TR>
<!-- AQI Values -->
<TR class='Data'>
<TD align=center>44</TD>
<TD align=center class='good'>Good</TD>
</TR>
<TR class='Data'>
</TABLE>
function AQICategory(AQIndex)
{
var AQI=parseFloat(AQIndex)
var AQICategory;
if (AQI<=50)
{
AQICategory="Good";

Much thanks for any help! Similar TutorialsI have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function: 1: I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100. Does any one know how to code this in my function below in javascript: Code: function insertQuestion(form)
{
var row = document.createElement("tr");
var cell, input;
cell = document.createElement("td");
cell.className = "weight";
input = document.createElement("input");
input.name = "weight_" + qnum;
input.onkeypress = "return isNumberKey(event)";
cell.appendChild(input);
row.appendChild(cell);
}
I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? I would appreciate if anyone could guide my point by point on how one could create a category picker just like gumtree (preferably in jquery): http://www.gumtree.com/add_posting.html?location_id=uk Specifically the points How clicking on a category opens another to the right How clicking on a category appends a variable like "#cat-10201" into the url (and vice versa) How css lists are used instead of form select menus (making it easily styled) How clicking on a deep subcategory automatically preselects all parent categories I'm not looking for anyone to actually code it for me (that would be outrageous ) but tips on how it's actually structured and steps on how it can be coded would be highly appreciated. I can do PHP and I know CSS also. I don't know plain javascript but I'm sure I can do most of it in jQuery Does anyone know the code/script that is used for the image slider and the category switcher (where it says Our Games) as seen on http://en.popmog.com/games? I have no idea how to create something similar on my own site.
I have search for about a week and still no luck. I need to dynamically display mutliple images using javascript, no hardcoding. The images have different categories. For ex. bellTower01.jpg, bellTower02.jpg...and fountain01.jpg, fountain02.jpg.... -Use JavaScript to display several images and scroll through them To display multiple thumbnails, arrange them into a small quantity (no more than 8 per page) Provide pagination I really really really need help. I have never done javascript before, so I'm still learning. I seriously checked out many threads and links but nothing works or is what I want. I hope someone can help me out and hopefully also allow me to become better at coding this kind of stuff. I am not allowed to code in php for this project. I can only use javascript to display the images. Also, I don't really need anything fancy, like slideshows or rotations, I just the image to appear when I select that specific category. I want to get the images from my folder/directory. Right now, I have it working as it just being hardcoded.

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! Hi, I have a string stored in a variable var = "4.25 houses". I would like to only extract the currency value, ie "4.25" from this. Is this possible? Also I would like to divide and multiply the new variable I get... does this number need to be converted or something? Thanks in advance! Hi. I'm trying to make a web page using javascript for validation, but after the last 2 functions I wrote, 2 functions don't work anymore. I attached the file so you can see for yourself. And I know there are a few things I could do to the html, but I'm saving those for last. Any idea why the scripts don't work is much appreciated. (the functions that don't work a "cont_pag1" and "cont_pag2"...btw...they worked just fine until I wrote the last few functions (the ones for the pag4 div))...And sorry for the really strange language...
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, I have a problem in javascript. When i am doing rounding of the value i am getting the o/p like 2.2e4. I have to display this value in decimal value(2.0002) not in exponential. Can any one please help me to resolve this issue.? Regards, VIjai 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 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 I am using a JavaScript price calculator. Right now it does everything I need except for one thing. If you look at the "type" field, they can choose either woven or printed. Right now, if they choose "woven" it adds 6 cents to to the total as you can see in this portion of the code: if (theForm.select.value=="woven") { priceeach+=0.06; Rather than 0.06, how do I get it to add a percentage--say 20% The form is located he http://goo.gl/YlJWo Thank you! I need to write something like this: http://justsheri.com/webscripting/wsassignment/1049950/ If you look at the code there is 52 of these <img src = './images/blank1.png' onClick='clickCard("qh",0)'/> where clickcard("numchanges", increments by 1) how is this done? Thanks Danny 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 This is quite easy yet hard. I'm trying to apply something in my forums, where a member could post something let's say: "Hi, I am number [random]1, 6[/random]" And what would happen is that, a number from 1 to 6 would be the content, for example, it would be: "Hi, I am number 3" But if you refresh the page, it would still be the same number. Like it won't be randomized again. So how do I make a javascript/html code that would make a one time number randomizer. I need help on some code
Code: function makefarm(){

Code: Coin:<input type="text" id="coin" value=50 size="1" style="background-color:transparent;border:0px solid white;" READONLY /> Lumber:<input type="text" id="lumber" value=100 size="1" style="background-color:transparent;border:0px solid white;" READONLY /> Iron:<input type="text" id="iron" value=25 size="1" style="background-color:transparent;border:0px solid white;" READONLY /> Food:<input type="text" id="food" value=100 size="1" style="background-color:transparent;border:0px solid white;" READONLY /> POP:<input type="text" id="pop" value=10 size="1" style="background-color:transparent;border:0px solid white;" READONLY /> so if i press the makefarm() button it will add to the numbers but if i press it again they will got to zero how could i make it remember the numbers?(the input boxes are the second code) I have a dynamic form that uses Code: var input_box = $("<input type=\"text\" id=\"ac\" >")
I need to have a unique id for each input that is displayed. How can I do this? I can't use vars or anything in there as variables don't work in this as it is? |
