Ajax :: Adding Data To Current Page And Removing Old
Sep 15, 2011
I've been learning a lot about jscript and PHP while I've been building my site...now I'm curious about using a little ajax. I have an internal email setup on my site where users can contact one-another...when you click on Inbox, Sent, Drafts, ect it calls a php script and reloads the page. I'm considering for my next release, doing this with jscript but my question is this...
When I print info to the page that I'm on, how hard is it to get rid of the old data that was there? This might be the easiest thing in the world but i don't even know what to call this on google. Also, if that's the norm, how hard is it to add data to a page with out getting rid of whats already there? I've been reading about ajax and I've been using jscripts to check my forms and do simple things but I'm really interested in learning what I really have the power to do here...
how I can use Jquery to append and remove data into a table by checking and unchecking html checkboxes?(Or any plugin for this?) I would like to generate an online order invoice from the following checkboxes:
< fieldset > <
[Code].....
I find these two example on the net but (The first example looks too similar to what I would like to do but with a table) but Icouldn'tfigure out how to modify them? [URL]
I would like to have two columns, the left column showing all available items with an add button. The right column showing all of the added items, and then adding these together to provide an order total, but with the ability for users to add to the quantity or remove from their order.I have the add item to order bit working on, and the sub-total is working.I started to try to add on add/remove buttons to the right #your-order column but am getting stuck.Every time a user adds another item to their order, more buttons are added, and I can't get the "remove item" button working.The page is located here:URL...Should I paste the jQuery code I am using here?
I want to remove the current DOM using tagName=DIV. Below function works fine in IE but not working properly in mozilla. The 'if' part is for IE and 'else' part is for mozilla FF. In 'else' part,The current DIV is not removing, only the DIV at position 1,that is the div at the first element in the array is removed.
how to remove the current childelement in mozilla.
I have page with an Ajax request which returns an entire <hml>..</html> page and I would like to use this response data to replace the current page. I wrote the following :
1. Take the current URL of the page and open a new window with a URL based on the current page. Some examples (I use "->" to mean "this URL turns into that URL"):I plan to use these bookmarklets in sequence, first pressing 1 to log into the CMS, then pressing 2 to edit the current page.
I use xmlhttpreq object to add data to the current html file. It will add to a specifiy place, like after a tag or before a tag And if it adds too many data after that tag, the whole page will become big and need to scroll down to see the latest added data how to let it scroll down automatically without any annoying scrolling down?
One way I can use is to use a anchor which is at the bottom of that page and after i put my data into the textbox and click the link( which is linked to proper file to process the data but also point to the anchor) the page will show from the bottom. but the whole page will first jump up a little space then jump down.
I am currently programming Script Adds data to the database but if i want to Shown the data that have been added Requires refresh the page to show the Data that have been added . and I do not want this method.I want to when adding data to show updates as soon as the addition of data.This can be done by Ajax , and An example of this method used Google Gmail.
I want to be able to add row at the end of the table with a 'remove' link which will remove specific row. The code I've managed to write so far:
$(document).ready(function() { $("#add_item").click(function () { var html = "<tr id='item_" + item_id + "' class='item'><td><a
[code]....
The problem is it wont instert the row at the proper place (after the last .item (class) and the remove link wont work for the last row in the table/list.
I am facing some problem with this when i am trying to sent the data in krnlAddComment1.asp page and there is only an insert query exists. after run the query successfully, response.write "...." revert back to me
I have a number of DIVs that I want to make 'selectable' on click, which means that I give the DIV you click on a class (just to show it's selected) and save its ID into an array. When I click on that DIV again, the class should be removed and its ID should be removed from the array as well. My code goes like
var selected_items = new Array(); $(".selectableDivs").click(function() { if($(this).hasClass("selected")) {
[code]....
But the alert at the end of the code always shows my a list of all divs I ever selected, even those that I unselected again. The IDs are just not removed from the array. Is that maybe because items saved in the array are not exactly $(this).attr("id") anymore?
I'm trying to make a form that will generate some code for game based on what they fill out. The code will be a modification menu of sorts. They will be able to name the menus and submenus and add or remove them if they want. I will need a way to get the information they filled in for each specific menu form, so I figure giving them each a unique id would do the trick. I'm sure there is a MUCH better way to do this, but here's what I have so far:
I have been doing research on parent object nodes & child nodes. I have a small problem with the code I made. What I need for it to do is depending on which link u click, it adds or deletes the node specified in the function. And the name of the div shouldnt matter as it should be used when clicking on the link <a href="javascript:addevent('divname');">Add Element</a>.
for instance:
"Add element" | "Delete element"
if u click on the add element, then it adds an element, and if u click on the delete element, then it deletes the added element.
Here is the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
This code was working originally. Then I had made some modifications and things weren't going right so I went back to how it was originally, and now it's not working!What this does is add a file text box when you click a button & then remove it when you click on its link. I get an error though when I click the Remove link saying that its argument is invalid. I don't understand why since its the exact same line of code the Add button has except assigned to a new variable.
This is the line that's coming up with the error: var d = document.getElementById('addToDiv'); in the removeAdditionalFile function. The error message says 'Invalid Argument'.
Here's the javascript:
function addFileTextbox() { var a = document.getElementById('addToDiv'); var b = document.getElementById('theValue');
I have a form on page1.php that will need multiple copies of page2.php to be placed or removed accordingly.
On page2.php it needs to have a select box (populated from a database) and a text area that will be posted along with the information on page1.php
Not sure if it'll help understand it, but basically page 1 has the employee's information, and they can add various details (and remove them) by pressing 'Add skill' then selecting a type from the drop down (communication, marketing, admin or whatever) and then a comment next to it.
I'm building an application where the user can add Questions. For each Question they can add x answers or remove them (see screenshot). I can add questions and add/remove answers, For each question that is added I update the 'gameQuestions' variable with 1; The same goes for answers that I add: for each added answer I update the 'counter' variable with 1. When I remove an answer, the app. doesn't know how many answers each question has, it simply decreases the "counter" variable. So when I remove the 2nd question, it doesn't know how many answers that 2nd question has! How can I store the number of answers per question and how do I remove them correctly?
Here's my code so far: $(document).ready(function(){ var gameQuestions = 1; var counter = 1; // Add a New Question... $(".addQuestion").click(function() { var question = "<table id='questionSet"+gameQuestions+"' class='form-table' style='background-color:#cccccc; width=100%;'>"; .....
I have a list of text-snippets which should be inserted into a textarea, separated by a comma. When I click the same text-snipped again, it should be removed from the textarea. I managed to to implement the "inserting" with the following code,
function quickadd() { $('.menu').addClass('red').delay(1000).removeClass('red'); }
So, from what I've gathered from the docs, this doesn't work because the addClass and removeClass functions don't observe the queue. How could I get around this and setup a function that will add a class, wait a second, then remove that class? Would it require me to go outside of jQuery a bit and use some standard JS?
I have a lot of information on my site that is in multiple categories. I have a list of categories, each with its own checkbox. By default, all the information is displayed (therefore all the checkbox's are checked by default).When someone unchecks the box I want to hide the divs with that class, and when someone rechecks the box, they should reappear. Here is my code so far. It is hiding the div's fine, but they are not reappearing when user tics the checkbox again.
<script type="text/javascript"> function toggledisplay(category){ if(document.getElementById(category).checked){
I have just got myself a copy of SWFUpload to show the progress of file uploads, however, it has a few problems, one of which I am trying to fix with the aid of jQuery. Essentially, if JavaScript doesn't load, then a standard input file element will be shown. But, if JavaScript is enabled, then jQuery removes this, and replaces it with all of the input elements that SWFUpload requires. Is this the best way of doing it, or should I be looking at another option? If so, how would I go about telling jQuery to remove and insert the form field, and each and every attribute the HTML will require?
I have a page that opens up an iframe for the user to be able to select photos. Each photo has a checkbox, and on select I add a hidden form element to the parent frame form. This all seems to work fine, but im now stuck on how to remove the form element when the checkbox is un-checked.
I'm trying to get my script below working. I've managed to get it to add fields dynamically but the remove function isn't right... and I can't think of a way round it. how can i incorporate a way for a limit on the number of fields that can be added?
<script type="text/javascript"> function addInput() { var x = document.getElementById("inputs"); x.innerHTML += "<input type="text" />"; } function removeInput() { [Code].....
ah, i've just looked into the operators in more details and -= is just for numbers... so this won't work. i presume this is going to be the wrong method then.
