Is it possible to make it so that when someone presses a certain key, or sequence of keys, on their keyboard a picture is posted instead of a letter? As in, if I type shift+c in a textarea or input box could an image be placed inside the textarea or input box instead of a "C"?
View 14 RepliesThe background of this thread is about CAPTCHA:
HTML Code:
<script language=javascript>
id=Math.round(Math.random()*2)+1
document.write("<img src="+id+".jpg>")
</script>
above is the js code I use to generate a random id, which in effect displays id.jpg on the web page (assume we have id.jpg in the right folder).
When a user sees that page, he is going to choose what word describes the picture best. (purpose of CAPTCHA: verify the user is a human)
HTML Code:
<select name="selected[1]">
<option value="">Click to identify</option>
<option>Clock</option>
<option>Dog</option>
<option>Ship</option>
<option>Tree</option>
</select></td><td>
The selection is sent to backend php script using POST method.
Here is my problem: In the php script, I know, for example, the user chose Dog to describe the mysterious jpg generated by js code. But there's no way for me to know the id of the jpg file generated by js code. Hence, I will not be able to check whether the user chose a valid description of the jpg file.
How can I send information about the id of the jpg file to the php script?
how you might use the onclick event to type a letter from the keyboard?
<img src="images/a.jpg" onclick="keyCode==96" />
I'm trying to convert only the last letter to an UpperCase letter. Example, I would need christmas to view as "christmaS", last letter to capitalize.
My code:
I have this hosting application on my website and people just seem oblivious to the fact that right next to the password input it says: "requires one uppercase letter, one lowercase letter, and one number"
I've tried to take the time before to locate a script, but I've never found a good enough tutorial.
The code is working 100%, but the only problem is with the function calling statement. It is working on the first img (picture) i want it to be called on the second picture.

I'd like to know please if there is a Javascript solution for enlarging pictures.
The outcome I am seeking is for the user to click on a thumbnail picture which then links to a bigger picture I dont want to use a HTML hyperlink.
Firebug's console is showing when visiting my test.html page Headers, Post and Response. In the Post tab it is showing: "id 9". I need to create a new page and get that 9 in it so I can use it. I don't mind jQuery, Ajax or Javascript but I need that 9. I know that with php I just need $_REQUEST["id"]; but I cannot use php.
View 5 Replies View RelatedI'm working on a form that I can add additional fields to dynamically (select fields and text input fields). I do so by clicking a button, which calls a javascript function, which in turn adds elements to the DOM. However, only the hardcoded (non-javascript created) fields are being POSTed. I assume this might have to do with the fact that the form uses tables to lay the fields out. The basic structure is similar to below:

This is similar to how forums work. I can't seem to find a way to do this so it's probably not available. Just thought I'd ask anyway.

The modified code looks like this:
I have a form which submits data to a php file, which than sends a pdf file containing the inputted data via php headers. So after the submit, you still see the page with the form on and get a pdf-download now I want to see if the pdf download-window came up and if so, redirect the user to another page (instead of the page where the form is on), but the window to download the pdf should be still there so the user is still able to download the file.
View 1 Replies View RelatedI am using ajax in my site and want to implement a friend request button. When a user clicks this button their userid and the userid of the friend thwey are requesting will go into a table called notifications in my mysql database. This works fine in regular html/php with javascript disabled but not when using javascript/ajax.
Here's my code which may clarify things:-
Code:
<script type="text/javascript">
function makeRequest(friendrequestloggedinuserid, friendrequestuserid)
{
if (window.XMLHttpRequest)
[Code]....
The above code works perfect if javascript is disabled and the button is clicked as the new row is inserted into the database however if javascript is enabled the alert shows inidicating the ajax file is working but the new row is not inserted. Is this something to do with the POST process between my javascript code and my ajax_processrequests.php file?
BTW $loggedinuserid and $userid are retrieved earlier on in my code but showing how they are retrieved is irrelevant to this because I know they are present at the point of the above code.
so just a simple questions maybe someone can help me out. I know nothing about java first of all but i do know in this code how to get rid of the comma - the only thing i need to change is to make it paste email results vertically instead of horizontally because it helps me collect emails from some older emails i have

How do I link a cookie, presented in a div, to a text box on the same page - so it can be searched?
Now I have a search box that link to the Google Maps API. I also have the two most recently search items to show up as cookies below the map. My goal is to have the cookies show up as links so that when you click them, they show up in the text box to search.
I'm thinking of three ways to do this and wonder which is the best way to do it.
1) Can I just adjust the div tag to link to the text box?
2) Can I adjust the function relating to how the cookies are posted on the page?

I am new to jquery. I am trying to return a string array with two strings back to a jquery ajax call. On success, when I try to retrieve the values, my result is just a string "System.string[]". How do I retrieve the values that I returned from the server in my call back function for success.
"success: function(result, textStatus, XMLHttpRequest) {"
how to retrieve the values of "result"?
I have a very large form and have a couple of checkbox groups where multiple items can be selected. They are grouped as an array of checkboxes. When I post the checkbox groups, the PHP script receives duplicate values. If the group has 2 checkboxes, 4 values are posted. If it has 10 checkboxes, 20 values will be posted.
i.e:
I then submit everything to a PHP script via an Ajax call, then output the result to a div. (see below)
However, when my PHP script loops over the $_POST array, it seems that each checkbox array is duplicated, so my PHP array returns:
This happens with all my checkbox arrays, but not with an array of hidden fields for some reason.
I don't think this is a PHP problem, as it looped over everything correctly when submitting via a conventional POST. I checked the contents of $_POST, and it seems that the duplicates are being posted.
It's pretty common to assign a click even to a <div> (or other tag), such as:
Code:
// JQuery
$(document).ready(function(){
$("div").click(function(){[code]....
Of course this event won't be accessible from the keyboard, which might be nice. Now if it where an <a> tag, you can do this:
Code:
$(document).ready(function(){
$("a").click(function(e){
alert("clicked");
e.preventDefault();
});
});
The click event will fire if you click the <a>, OR if you tab to it with your keyboard and hit Enter.My question is: is there a way to make elements other than <a> tags accessible in this way? I recently discovered if you define a tabindex on your div, such as <div tabindex="0">test</div>, you can tab to that div, but click events don't seem to fire if you use your keyboard. Are <a> tags the only tags that can work in this way?
how to make first letter capital using javascript
View 4 Replies View Relatedso i've seen javascript examples and some of the word uses
getElementById (i tried removing the caps and it won't work)
window.onload(work) and window.onload (won't work)
So how do i know when to use the caps as a first letter? And what is the name of this naming convention?
is it possible to have a loop that increments one letter?
for example
x='a'
while (x 'zzzzzzz')
{
//do something to increment a to b
}
once a gets to z it becomes aa then ab and ac and so on
is it possible?
