I have a script to prompt a user for 4 pieces of information.
-First name.
-Last name
-Area code.
-& Telephone number.
My assignment was to do this, and put the information is as follows.If both, first name & last name are entered, store in object as last name,first name.If only one is entered. display without the comma.Also store telephone number in (XXX) XXX-XXXX format.I was told to use methods to do all of these things.Please take note I am in a VERY basic javascript class.[code]
I am importing a Word Press blog to a web site, but it looks kind of sloppy. You can see it here : What I need to do is just present the title, and maybe the first 100 characters, then have a "read more" link. Once this link is clicked, the full article will show on the same page.
I think I might need to use a JavaScript library as well, but I know I will need some CSS. If someone could give me a general idea of how to go about this,
Im working on a spotlight effect using JQuery. Sample: [URL]I do not want a particular thumbnail to be highlighted on mouseover. So I tried something like this.
I'm trying to customize a script I found. It's about two select boxes, one for continent selection and one for country selection. When user selects a continent from the first select box, the second select box is filled with the list of the proper countries that belong to this continent.You can see that code of the script here:URl...In my page, the continent select box is loaded with a continent-value already selected (the selection depends on a database value) and I want to have the second countries select box, also loaded with the proper countries.I cannot make this happen, unless I change the continent's selection and trigger the onchange event. Can I someway keep the onchange event and also add the ability to have a continent and it's list of countries already loaded?
I embedded an external script to my website which output is generated on button click.This script creates inline styles which I would like to customize.I thought of doing so by adding
$('#submit').click(function() { initialize(); $('#divID div table').css("background-color", "#000");
I'm trying to customize the position of my labels through the option errorPlacement, but I still didn't find how to make it work, I want to display icones just after my inputs, and my labels in a div, I tried to use errorLabelContainer for the div, but still can't display my icons (you know, a simple check mark when the input is valid, and a red cross when not).
I have a javascript function that needs to access methods of a java object(localTag). In my JSP I'm trying to include hidden fields for the Strings returned from the getter method calls of the object like so:
If I can do something like this, what is the correct syntax and how do I access this property in my javascript? When I have a hidden field that is just a String, I access it in the javascript like "document.getElementById("theString").value" and it works fine, but I can't seem to find how to access the String value of a method call.
I am wondering if it is possible to get the response from a method within a given page, and that function alone? Traditionally, I have been getting the response from the Page_Load method of the targeted page, but now I want the response from a particular method on the target page:
Public Sub SomeCallback(ByVal sender As Object, ByVal e As EventArgs)
When you use addEventListener (or addEvent in IE) to call an object method, does it call it with the correct this parameter?
The ECMAScript reference has a lot to say about the caller using Function.prototype.call or Function.prototype.apply and passing the correct this pointer for the context, but how does addEventListener determine the correct this pointer. Or does it just punt and pass the global context, thus making it impossible to refer to the object this in an object method used as an event listener?
So I have this homework assignment where I need to get my application from switches to using methods to give me the same result. I usually am good in this class, but right now I am completely lost. Here is a piece of the code using switches:
/* Get Type of Math problem from the user */ input = JOptionPane.showInputDialog(null,"Enter the type of Math Problem" + "you would like to solve: " + "Addition = 1 " + "Subtraction = 2 " + "Multiplication = 3 " + "Division = 4 " + "Enter the number of your choice: "); .....
I need to get this same result by using methods. I can use these method signatures: public static int readProblemType(){} public static int getAddProblem(int randomValue1 int randomValue2){} public static int getSubProblem(int randomValue1 int randomValue2){} public static int getMultProblem(int randomValue1 int randomValue2){} public static int getDivProblem(int randomValue1 int randomValue2){} public static int readAnswer(){} Looking at what I need to do, how would I use public static int readProblemType(){} method to read the problem type? Or where should I start?
Programming assignment: Write a program for analyzing El Paso weather. This program must allow the user to enter dates followed by temperatures at these dates. Assume that we are only tracing one year, so the overall number of such dates does not exceed 366. Your must then output the following information:
*the average temperature; *the list of all the days when the temperature was below freezing (i.e., below 32); *the hottest temperature, and the list of all the days when the temperature was the hottest. Main difference: In the previous assignment, following our advise, you stored the dates in one array (array of strings), and temperatures in another array (array of numbers).
For this new assignment, define a class Record whose objects contain two fields:
*a field date that contains the date, and *a field temperature that contains the temperature. Instead of using two arrays, use a single array of records (i.e., of objects of type Record).
The problem I'm having, is that I do not know how to read from two files and store the information into one array. (For example: with this assignemnt, I need to have one array with 366 fields, and in each field there needs to be a date and temperature.)
I have more of a programme design related question here: I have an object with 2 methods, those two methods are supposed to be called repeatedly one after the other (e.g. by setInterval())
the problem with this code is that the execution time of those methods may increase depending on the processed data (an array with several hundred elements or more) so it may be, that the execution time of both methods exceeds the given repetition time. I could solve that by placing a call to the next function in each method, but I wonder if that is good design or not (tight coupling)
code for method2() is analogue Obj.prototype.method1 = function () { /* working code here */
I pulled out an old javascript object I created a while back a few days ago and I've been developing in Firefox ever since. Then I decided to test how it worked in other browsers and.....it works in none of them! Not chrome, not IE(7/8), not opera, and not safari.
It's built like this:
Code: function myCalendar() { //constructor function } myDiv.prototype.newMethod = function() {
[Code].....
It's really as simple as that....what's on the go? Do any JS experts out there know anything about this?
When a custom object is created in javascript, then methods need to be defined for this object. Still every object has toString() method available to them, even if it is not defined. How is this method available to all the objects ? Is it inherited from some root object ?
Is sort() method available to all the objects ? What are the other methiods available to all objects ? Where can I get list of available methods ?
I am a little confused how the memory for objects is allocated in JavaScript. David Flanagan, in "javascript: The Definitive Guide," states that each property of a class takes up memory space when instantiated. So space is created for aMethod three times in this example: Code:
I just wanted to know if there was any way to use script to display a list of methods linked to a particular object? The object I have in mind is getBrowser(), and I can't seem to find any documentation online with regards to it's methods.
Also, as I am learning, it would be nice to be able to know what methods are available for a particular object/function, without necessarily having to spend a while looking up an object's method when it's documented in a lot of different places, but only vaguely.
I have been trying to discover why the first() and last() methods are not working in my jQuery 1.2 nor 1.3 tests. After searching for a while, I found the alternative way with filter() and eq(), but I still wonder why none of those methods work.
The API documentation [URL]... states that they are available since 1.2, but they won't work, I always get a "not a function" error. I also found a tracker entry [URL].. discussing the need for them, but nothing is clear from it.
HTML5 brings two new methods to the js selector API: querySelector() and querySelectorAll(). These methods can be used to match elements against a group of selectors. I think, a lot of the functionality overlaps with jQuery selectors. My guess is that these new methods will be a few times faster than jQuery selectors because they are natively implemented. My question is, how will jQuery use these additions to the js selector API? Will jQuery selectors just encapsulate these new methods? If so, is this work in progress or..
Do many programmers remember most of the object properties and methods or do they use IDE or references to find those specific objects. I'm starting to learn Javascript and seeing all the different type of objects available can be depressing. :(
I am trying to create a function that takes a users input in the form xx/xx/xxxx. Then I need to figure out a way to compare to a new date and give which day of the year it is when using: alert("This is the" +foo+ "day of the year."). Im alittle confused on how to take the users input and compare it somehow to give me the day of the year.:cool:
