Make 422 (numbers) Works The Same Way As Just String Values In The Array/object Tree?
Oct 16, 2010
I have JS object w/ following structure:
PHP Code:
json_data_object.422.name
thta should of out put me "hello world" as it is what it is in array but it does not as there is 422 there That's my ID from database, and I gotta use itNow, if I change that ID to something in letters say to "i" then everything is fine. ex
PHP Code:
json_data_object.i.name
That one would work, but then I have to chnge JSON string thta pulls data from DB and i cant really do that...So the question is how can I make 422 (numbers) works the same way as just string values in the array/object tree?
I am starting to learn javascript and have been trying to make a image gallery. I was hoping to take an array of src and create a link for each one which when clicked on changes the src of an already existing img.My question though is how would I make the buttons for the numbers.I feel like a loop would work for this but I just can't seem to figure it out. I don't know how far off I am in thinking that through a loop I could create functions with a name plus the i variable.And in each function there could be something like:
Code: document.images["destination"].src = images[i] That would then produce an <a> with the href equal to the function name + "i" with the title being "i" as well.
Am I way off? How would I execute that? A little explanation about my code. I am going to be using a loop to add the images that will vary in amount for each page that is why I have the push function just for this test. And the document.ready is because I've been using some jQuery.
How do i use a function to find the average of the values in an array of numbers passed as argument to a function.(using java script) thank you for your help...
What I'm trying to do, I think, is to use elements of an array as a part of an object. Here's a lil' code snippet:
Code:
I'm trying to insert each of the elements of the katMusik-array into the checked-line, thus checking the checkboxes with those names. However, it doesn't seem to work.
Instead I get every char of the string each in one alert message. How can I transform the String to an Array, or get in this case the two key-value pairs?
I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 .what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object.
I am looking for the best performing solution for modifying and iterating an object graph in JavaScript. I have outlined below a simplified example of the object model and examples of how I will be using this graph.
Object model:
Two objects, [BadApples] and [GoodApples] each contains a collection of [Apple] items (500 max). [Apple] simply has an ID and a name.
Requirements:
A quick way of determining whether a certain apple exists in either [GoodApples] or [BadApples] (by ID).
A quick way of iterating through [GoodApples] and [BadApples] in order to update the web page.
A way of moving a certain [Apple] (by ID) between [GoodApples] and [BadApples].
I currently have this implemented using arrays, but iterating these arrays is expensive. Is there an implementation of a binary-tree for JavaScript? The real-world application may contain many hundreds of nodes, and performance is crucial.
Let's say I have a string, something like this: sadasd4assadasd8ssssda5asadasd3asdasdasd8dsdsd
and I want to pick out the numbers and add them to each other. How do I do that? I have tried and know how to pick out one number, but how do I pick out several numbers and add them?
I have a string like this: $433.00 As you can see it's a price with the Dollar sign, I need to convert that to an integer. How would I do that in Javascript?
I'm triying to convert a string (0000, 0001, 0002, 0003,0004,0007, ..., ... )in INT. Betwen 0000 and 0007 theres no problem. But the 0008 is converted to 1. I'm using
So my question is, if the above behaviors are the same?? If string is a number, and compare with another number, it will be the same behavior as compare 2 numbers?
In this case, it is comparing 2 strings that are numbers, so they are string comparisons here. correct?
if ("123" > "33") will return true
In this case, "33a" is not a number, that's why when it compare with another number, it always return false. correct?
I have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
I'm developing a web app and I want to validate a users input on a form. I need a regular expression to validate a string which must begin with a letter (i.e. A-Z or a-z) and must have 5 numbers (0-9) after it....
I know this is probable a easy one for most of you...But this is my first Javascript. I am trying to write a code that will add two numbers entered by a user and calculate the sum. When I wrote the code inside the HTML it worked fine. But I have to use a .js file and call the function from there. And now my code does not work.code...
I have an assignment that just asks you to input some numbers and then if the number isn't between 100-999 just to enter the final number and whatever the final number is to print out everything that is less then that number. For example: I enter 120, 128, and 1. It will then prompt me to enter the final number which I put 124. Now I have it set as 124 so everything less than 124 it will print. So I want the array to print 124, 120 and 1.
Code so far: <html> <title>Homework 5</title> <body> <script> var num = new Array(); var x = 0; var lastnum; for (x = 0; x < 3; x++){ num[x] = window.prompt("Please enter a number between 100-999:"); if((num[x] < 100) || (num[x] > 999)){ lastnum = window.prompt("Enter your last number:"); for (x = 0; x < 1; x++){ num.sort(); window.alert(num); } break; }} window.alert("DONE"); </script> </body>
I want to get the sum of all numbers in an text area irrespective of the spaces before between or after them. e.g. " 1 2 12 15 " =30
In the code below I can have multiple spaces or CR between numbers and it works giving me their sum But if i have a space before the first number or after the last number I get a NAN (
