I want the user to input their name and email address. after that, if they select a yes radio button, it means their data is in the db so I need to grab that data from the DB, and display it in different text fields. I am using Cold Fusion as my main language.
I was wondering if you can run a sql query in JS based around the email form field data, then get the data back, and use the returned data to populate the many fields on the page?
Please visit the following page if you want to see the page I am working with. The flower images at the bottom, when clicked, will display the src of that image when clicked in the textbox. However, I want to apply the same function to the manipulated images too, in order to get their data URL's. Currently, the images at the bottom have the following:
Code:
<img src="images/nem.png" onclick="clicked(this)" />
How would I go about adding the onclick to the following javascript generated images?
Code:
var dragon = new Image();
dragon.src = "images/flower2.png";
var dragon2 = new Image();
dragon2.src = "images/oldtraff2.png";
var dragon3 = new Image();
dragon3.src = "images/trees2.png";
var dragon4 = new Image();
dragon4.src = "images/f12.png";
var dragon5 = new Image();
dragon5.src = "images/nem2.png";
var dragon6 = new Image();
dragon6.src = "images/nl2.png";
var dragon7 = new Image();
dragon7.src = "images/dino2.png";
var dragon8 = new Image();
dragon8.src = "images/ipad2.png";
var dragon9 = new Image();
dragon9.src = "images/tokyo2.png";
var dragon10 = new Image();
dragon10.src = "images/pup2.png";
I should warn, i know almost nothing about javascript. i've been trying read sample scripts and examples on how to modify this script; but I just don't know enough. I have a script that pulls data from an array, and copies it directly to the clipboard when a user clicks on it. The problem is this only works in IE, because Firefox doesn't by default allow that to happen. I'm trying to change it so that when it is clicked, instead, it takes what was going to be copied to the clipboard, and puts it in a Prompt box for the user to copy and paste. I had other scripts that do that, but I can't for the life of me figure out how to learn from it!

I use following code to create an element and load data into it onclick:
("<div id="element" ></div>").appendTo('#content').load("grid.php");
The first time it loads very fast, 12ms.
I have a close buttons wich removes the element from dom: $("#element").fadeOut('fast').empty().remove();
The second time I execute the onclick event, the first code takes approx 1 second, so much slower. The php code execution time is the same as previously.
I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function
LoadDestinationTable() {
$("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.
I want to make it so that when I click on something, it changes what document.onclick does.
This is a simplified version of what I'm trying to do:
Code:
<div id="clickme" onclick="document.onclick = function(){ alert ('This should not be alerted on the first click'); }">Click here</div>
However, as you'll notice, the alert box shows up on the first click as well. The only way I have been able to get around this behaviour is to have the first onclick execute a timer that will then set the document.onclick after 1ms, however this seems very messy to me.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.
The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:
$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){

I would like to use jQuery to prepopulate a form - ie make a call to a php program to get data from a database and pre-populatea form with appropriate data for the user. Can anyone point me in the right direction for some examples on the simplest way to do this?

This is working fine on itself. What is does is when I click a link it loads data into the following div. When done loading it slides out. But I want to change the appearance of the slide. I have tried to do that like this: $(this).show("slide", { direction: "down" }, 1000); But this doesn't work. When I check firebug it says the following: o.easing[this.options.easing || (o.easing.swing ? "swing" : "linear")] is not a function

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.

If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-

I am trying to try jQuery 1.4.3 updated .data() method with HTML5 data attributes. The way I understood these changes is that an element with these attributes would automatically have their data populated by .data(). For example, if I have an element:
<ahref="#" data-cheese="cheddar">DataElement</a>
I can access this with .data('cheddar'). This part works fine. The issue I am having is that calling JUST data like $(this).data() just produces an empty object. Is this how it should be expected to function?
i am thinking of using a xml file as a data base for example , the xml file stores a list of reference numbers which is allocated to a url or a name such as 0123456789 and i have a text box on a webpage and the user types in a reference number and the javascripts reads the xml file to check if its a valid reference number i.e a registered number i am new to working with xml etc.
[Code]....
id like it to read the specific data thats contained within the tag such as 0123456789's tag = JOE
I'm trying to compare incoming JSON data to the existing data to see if there are any changes, but for giant objects like:
Code:
[{"date":"2011-09-03 23:06:03","notifier_id":"1","type":"1","unread":"0"},{"date":"2011-09-05 00:37:46"}]
if (JSON.stringify(oldData) == JSON.stringify(newData))
This doesn't seem to work. I've tried using:
Code:
escape("'" + JSON.stringify(W.notification.list + "'"))
but that ignores the objects properties and returns something like 22%5Bobject%20Object%5D%2C%5Bobject
Are there any plans to allow the .data() method to accept a map of key/value pairs of data?I don't think this is currently supported although many other jQuery methods support this type of functionality...
$('#myDiv').data({foo: true, bar: false});
I have the following sample code and when I click the a href link it pops up both windows.
HTML4Strict Code:
<tr false;" style="cursor:pointer"> <td>Some data</td> <td>More date</td> <td><a href="thatlink.html" false;">Details</a></td></tr>
In other words - linking the link that should open up 'thatlink.html' opens up that window first followed by the 'thislink.html' window in the table row onclick call.
I try to find working example, but no luck.I need this very simply javascript to onClick change value and second click change value back and third click change value again back and so on..
View 7 Replies View RelatedHow can I use onclick with the <div> tag?
View 5 Replies View RelatedI ran in to some trouble a couple of hours ago and can't get it to work..
The problem is that I have a div which has onclick and another div in that div who also has onclick. When I execute the second onclick the function is run twice (it's the same function).
<div onclick="toggle();">
<div onclick="toogle();"></div>
</div>
The toogle function checks if the div is visible or not and turns it and off accordingly. When the first div is on and the seconds get toggled the first one turns off.
I would like to add a function to some of my hyperlinks dynamically when the page loads ... I have to use onClick but I have no idea how to set it.
The little test I made should call a function to set the onClick of a link to display an alert box ... any help would be great.

I have an onclick() event handler wherein I want to change a value that then
needs to be shown in a textbox on a form on the page......can anyone show me
how this is done?
I'm currently working on a page the redirects to a necessary page by a drop-down menu. Currently it is only heading to one of the pages. I'm not quite sure what I'm doing wrong, but I was hoping someone could look at my code, and let me know what I'm doing wrong. Code:
View 5 Replies View RelatedI'm using the same style of form on a number of pages, but for some reason
the exact same one liner on one my pages doesn't do anything. The one liner
is:
<INPUT TYPE="BUTTON" onClick="location.href='admin.asp?sec=4&folder=32'"
CLASS="FormButton" TABINDEX=41 VALUE='Go back to list'>
Basically the user clicks this button and it takes the back to the main
page, which is actually the same page, but the 'sec' determines what routine
the page is going to run and display.
The above works fine on my other pages, but not on one particular page so I
must have something in this page that is stopping it from working, but I
can't see what.
If I put an alert before the location.href bit, eg
onClick="alert('hello');location.href='admin.asp..., then the alert does
appear when I click the button, which means it's my location ref that is
fouling up.
What is even weirder is that if I stick window. in front of the
location.href command then it works, eg:
<INPUT TYPE="BUTTON"
onClick="window.location.href='admin.asp?sec=4&folder=32'"
CLASS="FormButton" TABINDEX=41 VALUE='Go back to list'>
I know this solves my problem, but I'd like to know why this is the case.
