JavaScript - Prefix Required For Two Character Tostring(36)
I have the following code as shown below:
Code: <script type="text/javascript"> var a = 12; var b = 35; var c = 56; document.write(a.toString(36).toUpperCase() + "<br>"); document.write(b.toString(36).toUpperCase() + "<br>"); document.write(c.toString(36).toUpperCase() + "<br>"); </script> The problem right now is that for the first 36 number, it always miss the 'prefix 0'. From the code above, it will return the following: Code: C Z 1K My intention was to have all of them display in two character format, as shown below: Code: 0C 0Z 1K May I know how should I do it without having to use if (a < 36) else ... statement? Similar TutorialsI'm average when it comes to math so I'm having trouble understanding the concept of how you convert an integer to a string, and what would be the best outcome? Can someone help me understand the toString() method please?
Hi, I was looking at this code from another thread (code by Old Pendant) <script type = "text/javascript"> // constructor for a Car ojbect: function Car( reg, make, vin ) { this.registration = reg; this.manufacturer = make; this.VIN = vin; this.toString = function() { return "\nregistraion: " + this.registration + ", make: " + this.manufacturer + ", vin: " + this.VIN; }; } // Purpose: Gather car information and store it in a datbase // Ask user for REG info, CAR MAKE, car VIN var howMany = prompt("Enter details for how many cars?", ""); var cars = []; for (var i = 1; i <=howMany; i++) { var r = prompt ("Enter Registration Number for car No." + i,""); var m = prompt ("Enter Car Make for car No." + i,""); var v = prompt ("Enter Car VIN Number for car No." + i,""); cars.push( new Car( r, m, v ) ); } alert( cars ); </script> What I want to know is what this.tostring = function () does? And if this can be removed because with this there I can't put the code into a bigger function. I hope that has made some kind of sense, any help is appreciated... JavaScript has several implicit called function, including toString(), toNumber(), and valueOf(). I was wonderig that what is the prioprity of executing one of these functions when a JavaScript interpreter have a variable to be implicitly type conversed. And my second questions is what are the difference of toString(), toNumber(), and valueOf(). Because ECMAScript does not explain this clearly, is there any other document that I can have further reading? Thx a lot!!!! hi. i know php but learning javascript. can anybody give me a reason why i might not wanna use the php practice of beginning every variable_name with a dollar-sign: $variable_name??? i am just accustomed to seeing my variables beginning with a dollar_sign. Thanks. Hello all, I need assistance checking for valid characters in a username/password set up. I have been reading up on form validation but can't find exactly what I am looking for and need help deciphering what's going on. I have a list of accepted characters: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_@" a-z, A-Z, 0-9, dot, dash, underscore, and at. I want to then check an inputed string against that set and if a character is notin the accepted set, to send an alert. Here is what I have gathered so far: a for loop that increments through the values' .length - this is what checks each individual character. Then use of indexOf() can tell me which character is unacceptable. Now is where I am stuck and coming to you. Please help Hi all, I cant get this code to work because I do not know how to include the % character. Any help would be appreciated. My line break isnt working either Cheers, Adrian Code: rightButton.innerHTML = (rightOutcome1Prob+" chance of "+rightOutcome1+"\r\n else "+rightOutcome2); Specifically i was wondering if anyone had any ideas on how to select the specific character when hovering over a word? I have not been able to find any documentation on this however, there is a demo site i found for a plugin that allows character selection. http://labs.bitmeister.jp/moamoa/demo.html i dont need anything that large and elaborate... Edit I'm pretty wel experinced with jquery, I know it's possible with jquery Hi Im new to javascript and need some help with a project I have, the task I have is: Create a page that can take a bloke of text and out put the following o How many times each letter occurs o How many spaces o How many words o How many times each word occurs o A list of things that are not words or special characters I think maybe use an array but im not sure, like I said im new to this so not too sure on how to do it. I know it would read into a file say a txt file and sort through it this way, possibly using some kind of loop to read through all of the text before sorting it and I know it might use variables. I know how to kind of work through the task I have, but to actually implement the mechanics of the javascript is something that I then struggle with Thanks to all that help. I dont have much experience with javascript. Please provide javascript to create something like the image below: http://www.coolmicroscope.com/java.jpg Hi, I am not sure if this is the right place to ask, Currently i am running a small business with 25+ website. Due to testing purpose. I would like to have my site url to open in like 100 tabs without using much of the cpu usage and crashing down. can a script or bot be created where in you enter the url and it opens in like 100+ tabs hidden or visible without using much of my cpu usage. it doesnt neccesarly need to open in one shot it can open in like a few mints time, but its should stay open. will pay generously for your service. thanks ok I have a PHP form that I want to make Name Email and Phone required using javascript how would I do this here is my .php and html form.

So say if my string was.. Code: a = "Hello"; alert(a); How do I get it to say; Code: alert("ello");
So how do I take off the 'H' in this example.. Suppose I have the string 'ello'. I want to insert the letter 'h' in the beginning of that string. How do I do that without using a special function? I can only use the functions charAt and indexOf - anyone has any idea? H, I'm trying to create an sms form. but I want the users to be able to monitor the characters and sms number as they type...taking 160 characters to be 1 page. pls I'll need help with coding this form to display characters left in 'ch_count' box and number of pages in the 'pages' box while typing in the 'message' textarea....hope it's clear enough...thanks Code: <p> <textarea name="message" cols="" rows="" id="message"></textarea> </p> <p> <input name="ch_count" type="text" id="ch_count" size="8" /> characters left <input name="pages" type="text" id="pages" size="8" /> pages </p> Hey Guys, I wanted to prepend a character to menu items when the mouse will hove over them. An example of this is seen on the website of Minivegas, he http://minivegas.net/ When you hover over a menu item at the top a slash appears in front. There seems to happen a couple of things to smoothen out the effect of prepending the character. I was looking for a similarly smooth way of adding a character in front of my menu items. Can anybody help me out on how to do this? I'm also unable to find out exactly how they did it on the Minivegas website. Anybody any ideas? Thanks in advance! Regards, Roy Hi i need a little help on a JavaScript program it ask the user for a keyboard character and a number of rows and columns to look like this RRRRR R___R R___R R___R RRRRR and also this in another program rrrrrr rrrrrr rrrrrr rrrrrr I currently have <html><body> <script type="text/javascript"> // Declare variables and constants var userInputText; // user input to go var numRow; // number of the rows var NumCol; // number of the columns var ES = ""; // empty string userInputText = prompt("Enter a keyboard character",ES); numRow = prompt("Enter the number of rows",ES); NumCol = prompt("Enter the number of columns",ES); //need a nested loop to draw the character box </script> </body> </html> if any one can help me finish this program i would appreciate it Ok I have a textarea field that is validated by Js, this textarea can and will contain the newline character Code: \n so I validate in JS Code: if(textareaname.value.length < 200) this hten goes through to my php where i also check before I place in to the Database using MYSQL Code: if( strlen($_POST['textareaname']) < 200 ) but my php is giving me a different string length from my javascript. It looks as if Javascript is counting a newline as 1 character and php is treating it as 2. I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around. Any ideas? Any suggestions as to how I can make php and javascript treat a newline as the same amount of characters? Thanks in advance. I want to create dynamic Select option in form, I want that whenever user clicks on add member button then new row will get added & i have done that by taking help of DOM createElement method & I want that by using same, I want to create select option drop down list.
