JQuery :: Deleting From Array Of Local Storage Keys?
Dec 15, 2011
I'm trying to present a collapsible list if keys which when expanded will have a delete button at the end of it. My problem is that when this code runs, the confirmation alert shows the key name as the last one read from the array for all items. Here's the complete function:
[Code]...
why this code invokes the deleteNote function with the last key name for all notes?
I have some code that attempts to save a user's preference settings. It first tries to use "localStorage", and if that fails (only old versions of MSIE), then a cookie is used instead.For example, if I intentionally misspell "localStorage" by instead using "localStor" (simulating a browser that doesn't understand the object name), the code simply does not run.unfortunately, that doesn't work.
What Ive done is use local storage to set a value in my web app.
Then my next task was to write said value on my page (This took me hours but finally got it done).
My next task is using Setinterval(or what ever the correct way to solve my problem) to subtract a number (lets use "1" for this example) Every 5 seconds from the local storage value.So basically After I click the button. Value is set and displayed. After another button is click. Every 5 seconds the localstorage is subtraced by 1. I think the code im looking for is similar to this
I'm having some experiment with the new html5 features, I got the point where I need to store and retrieve data that I don't know it's key or value. It is appeared that there is no document about I want to do.How can I retrieve the first, the last and all record(s) ?
Now lets assume that the text itself contains characters outside of the normal ISO-8859-1 character set (like asian or russian characters). Would the individual char values be stored as one byte or two bytes?
"hello" -> 5 * 1 bytes = 5 (normal 8859 character sets) "hello" -> 5 * 2 bytes = 10 (unicode or an extended character set size).
Is ISO-8859-1 still stored like ASCII once was as 8 bits? Or is it 16? If I was to use a 2 byte character set then would that cut the size of my allocated local storage space by half?
Firstly, apologies for my terrible JavaScript knowledge! I'm getting there! I have an array that is made up of the results of a few SQL queries. The queries return the record id and an integer. I need to sort the results of the queries by the integer. I am trying to store them in an array, using the record is as the key, then sorting the array. However, when I try to get the data out of the array, it has changed the key!
E.g. Original results [10605] = 141 [10744] = 116 [18835] = 166 [15304] = 166
Given a JavaScript "array" (ok, so really they are "objects" but it's being treated as an array...) in the format
HTML Code: var patient_code = "0" var header_id = "1"; var question_id = "1000"; fake_data_array["patients"][patient_code][header_id][question_id] HTML Code: var fake_data_array = new Array(); fake_data_array["heading_information"] = new Array(); [Code]...
What's happening is, '1000', '1001', '1003', '1004' are being cast as integers, not strings, and it's "filling in" the first ~999 keys as 'undefined' so the length is returning something like 1005, not 7. I'm manually writing the arrays now, and will eventually be building this massive js array from a collection of existing PHP arrays. Is there a way to forcibly cast the values as strings?
I would like to have an array and define which element goes to what key. Something like this: Code: var test = [][]; test[0][0] = "foo"; test[0][1] = "bar";
However I am wondering if its possible to write it in one statement? Something like this: Code: var test[0] = [ [0] => "foo", [1] => "bar" ]; The code up doesn't work of course.
I'm trying to solve a problem with JS textbox array without success. I have two buttons in my page: PLUS and MINUS; at every click on PLUS a new textbox named 'dear' is generated. So, if one clicks, say, 3 times the output is something like:
dear[0] dear[1] dear[2]
The length property is accessible; alert(dear.length) gives Ɖ', correctly. The prolbem is that is not possible to delete a textbox, clicking on MINUS button. The thing I'd really need to do is to delete from the array (and in consequence from video) the last textbox created, when one clicks on MINUS button.
Pop() and Splice() methods do not work, unfortunely... This is the exact code of my page:
I am making a php/mysql epos system for my shop which will be run from a browser on my shop PC. I have large buttons which I would like to be able to 'click' by pressing something like the F-buttons at the top of the keyboard. Is it possible to override the standard button shortcuts for a web page. This is only going to be on my shop computer so accessibility is not a problem.
I am working on a project involving the Google Maps api. I have an application that spits out a text file with lat/lng coordinates plus some other info. I'm trying to figure out how to get the data from the local text file into a javascript array that can then be used by the Google Map api to create the map.
Any suggestions on how to go about doing this? I'm fairly certain that there is not a way to do it just with Javascript, but I thought I would ask. If not, any suggestions on how to do it, perhaps with xmlhttprequest and a PHP script? I don't need the text file to actually be saved on the web server, but if that's the only option then I can go that route.
What solutions would you guys recommend for storing data on the client? Is there something better than cookies? I've heard about the flash data storage, but, in my opinion, using flash for something as basic as client-side data caching is like using a sledge hammer to kill a fly.
Does anyone have a reputable reference about internal string storage in JavaScript? (for some particular implementation I mean).
Say having 1,048,576 characters long string from the geometric progression:
function generateLargeString() { var s = 'a' for (var i=1; i<21; ++i) { s = s.concat(s); } return s; }
- the internal size should be 2 mebibytes and not 1 (?) if strings are indeed stored as Unicode 16-bit. From the other hand it would be tempting for an engine developer do not spend extra bytes on ASCII chars...
So does anyone know of any documented engine optimizations on the matter? Would be expected on some engine to have the string from above twice smaller than say
function generateLargeString() { // 1200 ETHIOPIC SYLLABLE HA var s = String.fromCharCode(0x1200); for (var i=1; i<21; ++i) { s = s.concat(s); } return s; }
I'm attempting to track changes to values I've stored in the localStorage object. From everything thing I've read, this is done by adding a "storage" event listener to the window object but the test file I made doesn't seem to fire the event. I was under the impression that there was pretty good support for this (although I do realize the spec is still under revision).
Code: if(localStorage) { // Set Item button1 = document.createElement("input");
[Code].....
I create two buttons on the page - the first to write a value to localStorage (which works) and the second to clear all values from localStorage (also works). The problem is the event just does not want to fire for me. Even if I set the event on the window's "onstorage" property rather than use addEventListener, no event fires. I've tried in the most recent Chrome, Firefox and Safari browsers.
i am working as a llinux admin, in my company we are using Apache-tomcat to host the web server.
[URL]
check this url and i need one clarification in this image it clearly display the size of the mail box i 3mb and you are used already 21% like that,
this same scenario only we are going to use in our application , we are developing a H.R based application in that if client bought space from us.
for example if the client bought 250 mb space from us means, we need to intimate like that image which i posted above, -- ur using space is 250 mb ur alredy used 200 mb like that.
for this how is it possible using java??? and for this any server side works are there or using front side application itself we can finish this task?
I'm trying to figure out how to select a value from a list that is filled dynamically using ajax auto suggest Take a look at the small code: when typing in a name by the keyboard this function is called:
I'm trying to look for images that contain 'x.jpg' and remove its <img> container. I'm using the :contains and remove feature without success. What am I doing wrong?
Now I am trying to delete a node directly from above EmailXml , though it is possible with above code when case matches with my Type, I can do some string operations and get the result. But is there any other method which removes the node directly ?
I'm using jquery to pass trough data to another page where I want to insert and delete a record. But the problem is that jquery only inserts or deletes the records and not both together. I use following code: For jquery: $(document).ready(function(){ $("#btnAddPayment").click(payment); }); //example 1 function payment(){ $.ajax({ type:"POST", url: "acceptPaymentExecute.asp", dataType: "application/x-www-form-urlencoded", .....
objRS = objConn.execute(strInsertPayment) objRS = objConn.execute(strDeleteMemberPayment) objRS.close() set objRS = nothing objConn.close() set objConn = nothing The queries work but not together. If I comment the insert statement, my page executes the delete statement. I already tried to call another object for my delete statement but it does the same.
