JavaScript - Dynamically Calculate Padding-left
Hi,
Here's a sample division: Code: <div style="padding:0 0 0 30px; background:url(http://www.google.com/help/hc/images...ent_bubble.gif) left center no-repeat;">some text</div> I wonder how I can calculate the padding-left:30px dynamically so that any icon I choose the padding-left value changes according to the image width. Any help is appreciated! Similar TutorialsHi, Here are sample divisions: Code: <style type="text/css"> #grandparent {width:100px;} #parent {overflow:auto; height:100px; } .child {overflow:hidden; margin-left:10px;} </style> <div id="grandparent"> <div id="parent"> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> <div class="child">1000000000000000000000000</div> </div> </div> The <div class="child"> width value is always 10 pixels less than <div id="parent"> width value. How can it be calculated so any width value is given to <div id="parent">, its child gets 10 pixels less than that? Any help is very much appreciated! Mike Hi everyone, I am pretty new to JS and I am looking for help writing a function that will dynamically calculate filed values. I have a PHP-generated form which may have a varying number of fields. I need to: 1. calculate the line total for each row -- unitprice * units = linetotal 2. calculate total of all linetotals. I have named my fields as follows: unitprice[1], unitprice[2]... , units[1], units[2], ... I have the following calculate function: Code: function calculateOld() { // get both values unitprice = document.forms["invoice"].unitprice.value; units = document.forms["invoice"].units.value; // do some calculation lineTotal = formatNumber((unitprice * units), 2); // set the value in the right field document.forms["invoice"].linetotal.value = lineTotal; unitprice2 = document.forms["invoice"].unitprice2.value; units2 = document.forms["invoice"].units2.value; if(unitprice2 != '') { // do some calculation lineTotal2 = formatNumber((unitprice2 * units2), 2); // set the value in the right field document.forms["invoice"].linetotal2.value = lineTotal2; document.forms["invoice"].totalprice.value = formatNumber((parseFloat(lineTotal) + parseFloat(lineTotal2)),2); } else { document.forms["invoice"].linetotal2.value = ''; document.forms["invoice"].totalprice.value = formatNumber(lineTotal,2); } } This does calculate what I need but only if I have up to two rows. I need to make the function dynamically count how many rows there are, and calculate the linetotal for each row. And here's where my limited JS knowledge brings me to a halt. I have been thinking about what this new and dynamic function should look like, but that's the best I could produce... Code: function calculate() { var unitprice[i] = document.forms["invoice"].unitprice[i].value; var units[i] = document.forms["invoice"].units[i].value; var linetotal[i] = formatNumber((unitprice[i] * units[i]), 2); return linetotal; } Your help will be appreciated. Please explain how things are done, don't just give me the code. Thanks in advance! hi, I've got a problem and i really need help. this is my code <script> var y= new Date(); y.getFullYear() + '<br />'; alert(y); var year = new Date(); year.setFullYear(prompt('Enter the year','1990'),prompt('Enter the month','1'), prompt('Enter the day','1')); alert(year); var yy = y-year; alert(yy); </script> i want when a user write his/her birthday JS calculate the age. that's all I have tried many time to make the calculation to appear at the total text box. however, I fail to find where the problem is.

I wonder is there any javascript to calculate IP length For example I have Start ADDR: VLAN_ADDR which is: 10.52.28.0 Stop ADDR: VLAN_LAST which is 10.52.29.254 As I know:result is 512 or another example: Start ADDR: VLAN_ADDR which is: 10.52.64.11 Stop ADDR: VLAN_LAST which is 10.52.64.15 As I know:result is 5 How to count it in javascript code ? Results are "numbers" Best regards Leos. I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live? So if the current value is 5 and I change it to 6, it will automatically recalculate the new value. You can see what I'm working on he http://sheetmusichaven.com/admin/mys...calculator.php Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date. hi, i need a help for experts out there. i've a set of questionnaire with 10 questions.answer for each question to choose from is 0-6 using radio button.for all the questions answered i need to calculate overall percentage based on the scores. i've done the html coding but having problem with javascript..is there any websites i can refer to write a coding or anyone can give example how to do it. pls help.. anyone would you help me I have some problem to calculate PHP Code: <table width="415" cellspacing="1" cellpadding="1"> <tr> <th width="151" scope="col">Price</th> <th width="189" scope="col">qty</th> <th width="63" scope="col">total</th> </tr> <tr> <td><label> <input name="price" type="text" id="price" value="2000"> </label></td> <td><label> <input name="qty" type="text" id="qty" value="2"> </label></td> <td><label> <input name="total" type="text" id="total" value="4000"> </label></td> </tr> <tr> <td><input name="price" type="text" id="price" value="2000"></td> <td><input name="qty" type="text" id="qty" value="4"></td> <td><input name="total" type="text" id="total" value="8000"></td> </tr> <tr> <td> </td> <td>Total</td> <td><label> <input name="gtotal" type="text" id="gtotal" value="12000"> </label></td> </tr> </table> How to calucate it from price * qty = Total and gtotal=sum of total, in the first rows. Ican do it if there is one row, but i dont know how to calculate samae name of text field like in 2nd or more rows I am working on a form that has 15 rows for order entry. These rows are called: qty | part | desc | cost | amount I have the following ASP code that generates the rows: Code: <% For i = 1 To 15 %> <TR align=center><td><input type="text" NAME="qty<%Response.Write i%>" onChange='DoMath()'></td> <TD><INPUT TYPE="text" NAME="part<% Response.Write i %>"></TD> <TD><INPUT TYPE="text" NAME="desc<%Response.Write i %>"></TD> <TD><INPUT TYPE="text" NAME="cost<%Response.Write i%>" onChange="DoMath()"></TD> <TD><INPUT TYPE="text" NAME="amount<%Response.Write i%>" readonly></TD></TR> <% Next %> This gives me the following fields in the form: qty1 | part1 | desc1 | cost1 | amount1 qty2 | part2 | desc2 | cost2 | amount2 etc. My Javascript (DoMath) to calculate the row totals looks like this for now: Code: <script type='text/javascript'> function DoMath(){ var Units = document.PlaceOrder.qty1.value; var Rate = document.PlaceOrder.cost1.value; var Total = Units * Rate; document.PlaceOrder.amount1.value = Total.toFixed(2); document.PlaceOrder.grandtotal.value = Total.toFixed(2); } </script> This works fine for the first row, but I need it to scale for the rest of the rows, and also allow for future addition/expansion. Unfortunately, I am Javascript-tarded and can't figure it out, despite numerous examples online... I also need to find a way to recalculate the "grandtotal" box on the form based on whether or not the checkbox called "taxChecked" is checked. If the user checks it, I need it to recalculate the "grandtotal" field with a tax rate, and if they un-check it, it should recalcuate "grandtotal" WITHOUT the tax rate. Any suggestions or pointers are greatly appreciated!

For example "You got - 5 out of 5" "Time Taken - 3 minutes" "Date - 24-06-2011" Thank you. Can anyone help me with the following Javascript. I am going crazy trying to figure this out because it should be easy. Basically I want to calculate the percentage of a number, but I'm getting a really weird result. In the following code f is equal to 3 and x.length is equal to 8. The part that isn't working is emphasised in bold. Basically 3/8 * 100 should result in 37.5 but the result I am getting with the following code is 7934570.3125. How do you calculate this percentage in Javascript? Code: function displaymember() { var m = 1; var f = 1; for(i=0;i<x.length;i++) { sex=(x[i].getElementsByTagName("sex")[0].childNodes[0].nodeValue); if (sex=="Male") { m++; } else { f++; } percent=f/x.length * 100 document.getElementById("fixed").innerHTML=percent; } } |
