Way To Determine Coordinates Of Form Input On The Fly?
Jul 16, 2010
looking for the best current way to determine the coordinates of a form's text input that the user just clicked, so that I can use that info to dynamically position a select menu that I will make become visible just below that text input.I am finding all kinds of things.. but most are unclear to me, or worse.what they feel is the proper best current way to go about this
I created this test routine to return the form containing a certain input element:
function GetElementForm(element) { // Return the form that contains element.
varmyElement = element;
while (myElement) { myElement = myElement.parentNode; if (myElement) { var sTagName = myElement.tagName; if (sTagName) { if (sTagName.toLowerCase() == "form") { break; }}}} return myElement;}
This seems to work for "well formed" HTML, but fails for example, when a form is defined within a table.
point.x and point.y values get submitted to the server specifying where on the image I have clicked.
Is there any (simple) way to get ahold of that point.x and point.y BEFORE they are sent to the server (and prevent that from happening)? Ie. I just want the points where someone clicks on an image and not interested in a submission to the server.
I have a script that I want to run only when my input box IS NOT disabled. Can someone tell me if something is wrong with my script? Is "disabled" the correct property to use?
function TextChanged(i){ if (!document.ScheduleForm["txtGrossPayroll" + i].disabled) { document.ScheduleForm.txtRecordStatus.value = "Changes Made; Record Not Saved.";
I would like to test if a particular input field has focus before allowing an event to take place. How can I do this, I tried using:
if ($('input#div_name').focus()) { do_something... }
But I guess many of you already know that in this case all it did was transfer focus to input#div_name - Which is not what I wanted to do - I wanted to only test if input#div_name had focus.
i have to draw a line between to different coordinates which are going on google maps so for example :
[Code]...
the above coordinates are in xml format which, i later call in Java script functions and display them on the map as a simple pointers what i need is from one point of coordinates to another point of coordinates Java script would draw a line which would represent the direction from one coordinate to other .
I need the code for if the user enters in a code into the field for example E1 and clicks submit it'll redirect them to a certain form. And if another user entered in E2 it would redirect them to a DIFFERENT form.
I have a simple problem: mark a list of defects on an image.
I think the best way to do it is to select a single deffect, then take two coordinates of coursor form an image on a web page (first when user press the button, and the second when he releases it). Those two points are going to be send to the web application (i.e. with AJAX) and saved in a database. Later, I will use those points to render the image with RMagic (drawing the lines and defects list numbers on top of the image).
How do I determine whether a variable exists in a form. I have a form called "theForm". I want to determine whether the variable "THIRD_PARTY" exists in the form and if it has been set.
alright I'm writing form which calls out a function F1 onsubmit but I want it to do that based on what the user answers to the last question on the form
this question has a yes/no answer, if the answer is yes, I want it to call F1 as it would and the function basically sends the form contents to two different places, if the answer was no, I want it to just submit it to one place.. Code:
Im trying to find the correct syntax to use to determine whether which form element is visible on changing the value in a dropdown list I need something in the onChange of the dropdown list that will cause the appropriate element on another part of the page to be displayed Code:
var mydropdownlist = document.questform.typeid.options[document.questform.typeid.selectedIndex].v alue; if(mydropdownlist<6) then display <input name="ans1" type="text" > else display <textarea name="ans1" rows="1" ></textarea>
I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.
I have a form that has a reset button, and when it's closed, the form is reset. However, at least in testing on my own machine, I notice that the form fields are remembering past input (on Firefox 4 anyway). Once this goes public, I don't want the form remembering anything in case the website is viewed on a public machine. How can I keep the form fields from remembering any past input?
I am trying to get the X and Y coordinates to have a pop up form to use as reference, this is a shopping cart so the more items in the cart the further down the page the form needs to open,
I'm trying to build a simple image-map-creation tool for a web-based app I'm making. (User selects an image, then clicks on it to set image map areas; initially could be just RECTANGLE, later want CIRCLE and POLYGON.)
The quickest "solution" was to display the image with anchor tags, with the ISMAP option on. This causes the x/y coordinates to be displayed in the status bar, at the end of the URL. Sweet, but I'd like to be able to tell when the user clicks, and then grab those values. Then I can build a text string holding their selected area, etc. (It'd be great if I could show the selected area with a box or something, too, but that may require doing it in PHP, building images, etc.) Anyway, does anyone know how I can get the X/Y coordinates when the user clicks? Since it's in a form, can I do something with input types to get the values?
how to find the coodinates for a picture in a middle of the page for example with js? I need this because i have a js script that get the mouse coodinates (X,Y) for the page.I have to modify this script to work only at my picture area and to get me the coordinates for my picture not the coordinates for my hole page. Code:
do ya know an efficient way to get the coordinates of a pictures so that I can use them to create a map? It is a rectangle. Here is the code I set up for a page:
I've got a image zoomer set up using a script located in shiftzoom.js. Basically, the XY coordinates of the mouse are shown in the bottom left of the image as the mouse moves. However, when I am zoomed right out the coordinates are limited to that of the image 'canvas' size (1024,768) and as soon as I zoom in, the coordinates of the mouse (which is in the same place) change until I am fully zoomed in and the coordinates are limited to the original image resolution in the corners. Hope that made sense... This is the relevant code in shiftzoom.js:
