I have a script that inserts a Smiley into a textarea for a forum script I'm working on.It works, except that the insertion will only appear at the end of all the existing text.Is there some way to have the smiley insert at the cursor point?
Code:
function AddText(form, Action){
var AddTxt="";

I'm not very well versed in javascript. I'm trying to make a bookmarklet that when I click it will either append text to what I've already written or insert the predefined text at the cursor's position in a textarea. Also the browser I'm trying to do this on is Chromium.
Here's what I have:javascript:void((function(){document.getElementsByTagName('textarea')[0].value='ಠ_ಠ'})())
but this of course changes the entire value of the text field to: ಠ_ಠ...rather than appending or inserting at the cursor position. I'm guessing append would be the simplest, though cursor position would be most efficient.
I'm looking for a function that I can use which will do the following when the mouse cursor is in a textarea:
know which textarea to work with based on current cursor position (not sure if this possible, couldn't find examples) - i.e. just 1 'Bold' button to operate on multiple textareas.
insert tag or tags (i.e. ,[image]) at cursor position, if text is selected then insert tags around text selection.
Is there a method to get the x and the y coordinates where a user click in
the screen?
How can I get the position in a image area in where I do clic?
If I have a jpeg image 400x500 and I do clic on 200x100 the script returns height=200
width=100
Can anyone please help/direct me to find/write a simple Javascript function to clean up a decimal point or a coma on a number.
For Example I need
10.000 to become 10000
or
10,000 to become 10000
I just wondered how I can refer to the following two
textboxes in this form:
<FORM action="FormWrite.php" method="post" name="submitForm">
<INPUT NAME="inputValues[etunimi]" SIZE=40>
<INPUT NAME="inputValues[sukunimi]" SIZE=40>
<INPUT TYPE="button" onclick="javacscript:sendForm();"
VALUE="Lähetä">
</FORM>
the reason the [] signs are in the name is to get all the textboxes values
in one variable
when using a php script.
- But how can I refer to it with javascript? For example; I tried
alert(document.submitForm.inputValues[etunimi].value);
I'm using a third-party chat application. They require that form field
names be formatted "SESSIONVAR!FIELDNAME". The bang is creating
headaches when I try to write validation script. How can I handle this
format properly? I'm not sure how to escape the exclamation point
within my code.
<form action="..." method="post">
<input type=image name="Image1"
src="..."/>
</form>
When I click on the image the form submitted to the server. As I can
see post data contains next additional values: Image1.x=121 and
Image1.y=64 These values are coordinates of clicked point relative to
image.
Can I get these values in onclick event handler (within the
beforeSubmit method)?
what's the point of using x.constructor.prototype? (highlighted in red) why not directly use x.prototype. classname to check whether 'classname' property is in this class?

View 4 Replies View RelatedI'm trying to utilized a more object-oriented approach to managing
window events in javascript. Thus, I am creating a "controller" object
to handle events and interact with the server. However, I apparently
don't fully understand what "this" refers to. In the code below I was
expecting that when the button was clicked (handleDeleteButtonClicked
function) that "this" would be pointing at a ViewController object.
Instead it was the Button (HtmlInputElement).
<html>
<head>
<script>
/* Constructor */
function ViewController() {
this.foo = "bar";
}
/* delete button handler */
ViewController.prototype.handleDeleteButtonClicked = function() {
window.alert("delete clicked, this=" + this + " this.foo= " +
this.foo);
};
/* initializer */
ViewController.prototype.initialize = function() {
document.getElementById("delete-button").onclick =
this.handleDeleteButtonClicked;
};
</script>
</head>
<body onload="javascript:new ViewController().initialize();">
<input id="delete-button" type="button" value="Delete">

I am doing a virtual point of sales page. Once the user has paid, he should be readdressed to the original web page. But this doesn't happen. I have realized the payment bank code is window.opener.location='[URL]'. I have copied their code and changed that by window.open ("[URL]") and it perfectly works. I have replicated the situation in these links...
The one that doesn't work [URL]
And the one I have modified and works [URL]
They insist their code is ok. Obviously I cannot modify their code located in their server.
I use the following to round off to two decimal point.It works fine
function roundNumber(rnum, rlength) {
var newnumber = Math.round(rnum*Math.pow(10,rlength))/Math.pow(10,rlength);
return newnumber;
}

View 3 Replies View RelatedI've created a page with an image of a man where a user is able to click on an area and a div is positioned at that point containing a white circle. This code works in all browsers except IE 6 where it creates a duplicate white circle beneath the one which is placed in the correct location. How to get rid of this second circle?

I understand that there is no need to initialize a variable at the point of declaration. OTH, what is the default type of a [declared] variable? For example:

I wrote a regex to edit a decimal number. you're allowed 1,2, or 3
digits before the decimal point, and 0,1,2,or 3digits after the decimal
point. Of course, you can't enter a decimal point without at least a
digit after ("5." is invalid). So here is my regex
pattern=/^d{1,3}(.(?=d))d{0,3}$/
This works fine for every case except an integer. In other words, it
tests false for entering 5, or 567.
I don't see why it tests false for integers. I'm allowing 1-3 digits
before the decimal point, then a decimal point only if the next
character is a digit (the lookahead clause), and then 0-3 digits after
the decimal point.
I've gotten around this problem with other javascript code around
the regex, but I'd just like to know why this "clean" solution doesn't
work.
How can jQuery locate a non-predetermined DOM insertion point? My application relies on custom code to "bootstrap" itself. I'm wondering if similar functionality is available in jQuery?
My app works in the following fashion:
- user places a script tag in their web page.
- my script fires and performs the following routines:
- scriptLocation = whereAmI()? (find scripts in document, length -1)
- insertBefore(DIV, scriptLocation);
- use DIV as canvas, DOM target for all that follows
- install application in DIV
Note that my custom app does not wait for any kind of "ready" state. It has no dependencies on the surrounding document. It fires inline. My impression is that jQuery's approach ("Find something, do something") is incompatible, because it relies on a known DOM insertion point. It would seem straightforward to "query" the DOM, and find an element of known ID. That would conflict with my business constraint; I have no control over the destination page. Are my assumptions about jQuery true? Or is there a way for a jQuery script to wake up, find its location, and the install elements there?
a simple "../" doesn't seem to work :(
let me know if there's any information I can provide.
