So if I add 1 rows, I get 2 text boxes with the ID of 1-medication as I already have a row in place (static) This works fine. However when I try to get the value of 1-medication, I thought I'd get something like value1,value2 but instead I just get value1 If I change the function above to putput a text box with ID of 2-medication, I can get the value of that by itself just fine. why if I have more than 1 item with the same ID, I can't concatenate each value?

View 3 Replies View RelatedI am making a small image annotation tool for research purpose. I have many images shown to a <user> and the person has to click on the image to enter further information about the image.
I would like to POST information about the <user> which is same for all images and also some fields containing the image information to php page containing next level of processing (the page is again same for all image and takes the user and image information as POSTed information).
So I was wondering if there could be a javascript function which i can put like onclick=submitform(imgname, imgA etc.) which submits a FORM with user information (same for all images hence not passed) and image information (strings containing info abt the images e.g. name, quality rating etc.) fields to another php page.
I could put forms for each image but I am dealing with hundreds of images here.
I'm trying to use a variable that is passed into a function to to dynamically name an instance of an Object(). I've created a Timer() Object that seems to work just fine... the problem is I can't figure out how to pass in an instance name into setTimer() to create a new instance of Timer() object?? My ultimate goal is to have multiple instances of the Timer() Object running at once. While the code below works it only allows me to create 1 instance of the Timer() Object with the name of tmp.

in Javascript I need to dynamically assign the values of textboxes from an array. For example, The textbox ids are box0,box1,box2 and the array is [0,1,2]. Here i need to assign 0 to box0 and 1 to box1 and 2 to box2.
View 1 Replies View RelatedI would like to have a jsp page with a form consisting of several inputs and selects. When page loads for the first time, there is only one select (with values taken from database), but after clicking on link "add", the subsequent selects are added (using JavaScript and DOM). It seems to be pretty easy task, but I'm not sure how to populate the newly created select with data.
View 2 Replies View RelatedHow can I dynamically change the color of values on a page, to show if they are above or below a target value entered in a text box on the page. Those below should be shown in green, those above in red, and identical (equal) should be in amber. Values can be put in a particular tag and then use the getElementsByTagName.

I've tried numerous variations of the alert line with evals, brackets and jQuery syntax but always seem to get the error:
XML filter is applied to non-XML value ({one:["1", "2", "3"], two:["a", "b", "c"]})
Which makes me think I'm either attempting something stupid or only missing my target slightly.
The code will be running within a jQuery project up if that helps in any way.

When submitting a form, I would like to check the values of some fields first. These fields are dynamically generated by javascript after the page has loaded (that is, a user selected a value from a dropdown between 1 and 10, if 2 is selected, 2 inputs are generated, if 7 is selected, 7 inputs are generated etc). I think I understand that Jquery isn't aware of these items because they were created after the DOM was scanned. Is there any way I can 'refresh' jquery to make it aware of these new items?
View 1 Replies View RelatedI am trying to assign values to a bunch of form fields. However, I don't want to loop through EVERY field in the form, just a specific subset of fields. The fields I am trying to change are all named similarly myField1, myField2, myField3.So, my thought is that I would like to use a for loop and loop through the appropriate fields by simply incrementing a variable and appending it to the end of the string "myField" in order to change the appropriate field.How can I evaluate "myField + iterator" into a useable reference to change the value of said field?
View 6 Replies View RelatedI have a form, and i am trying to add the values of 5 fields into one javascript variable. Then i need an ajax function to search a directory for a php file made from these variables and return a "file exists" or "file doesnt exist" message to the form.
For example, assume the following values have been inputted into the fields;
Field1 (Manufacturer) - Kawasaki
Field2 (Model_Name) - GPZ500
Field3 (Nickname) - None
Field4 (Market) - UK
Field5 (Year) - 2000
Then javascript needs to add the values of Field1 - Field5 (and add a few bits)to create (for example):
Kawasaki_GPZ500_None_UK_2000.php
Then i need ajax to search a web directory for the file above, and if it exists return a link, or if it doesnt exist tell the user it doesnt exist.
im hoping that i can use ajax to do this search without clicking any buttons etc. unfortunately i have very little knowlegde of javascript and ajax and dont have a clue how i can go about implementing this.
i know how to do it by posting the variables to the next page and doing the check using php - but i would like instant validation as soon as the form fields have been entered.
I am calling this javascript function:
var facing = "First";
function switchit(list){
if (list != facing){
[code]....
Finally i got what i want but whar is missing is how how can i get those dynamically textboxes / Dropdowns strored or capture and stored into a database table.Un employee can go and select projects he is working on then the current 6 months time assignment to this project: each row or line is 1 project with respectibe assignment time.

According to W3Schools (which I've been warned to stay away from), browser cookies are just text files. This tells me that ALL cookie data is ALWAYS of string type. Is this true? Is it possible for a cookie to be an object, or an int, or anything other than string?

I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
