I've boiled down my code to the essence of the problem; a variable which serves as a parameter to a function keeps coming up as 'undefined'. The code is quite simple:
I have a single page with a single form, but I have split the form into 3 divs for styling purposes. I have some java script that is supposed to pull values from the text fields, and put them in a selct box using 'document.forms[0].name.value', but nothing is happening. I am wondering if having the form split into to divs is causing the JS to not be able to find the fields, using the forms array? Here is the form portion of the html code:
I am trying to use my date Object function to get the date from the comp but my variables in my function are coming up undefined.
Here is my function: function displayTime() { var currentTime, hour, minute, second, range, m, s currentTime = new Date() var hourInt = currentTime.getHours() var minuteInt = currentTime.getMinutes() var secondInt = currentTime.getSeconds()
if (hourInt > 12) { range = "PM" hourInt -= 12 } else { range = "AM" } hour = String(hourInt)
if (minuteInt < 10) { m = String(0) + String(minuteInt) } minute = m if (secondInt < 10) { s = String(0) + String(secondInt) } second = s document.timeForm.timeBox.value = hour + ":" + minute + ":" + second + " " + range alert(hour + ":" + minute + ":" + second + " " + range)
I am having some fun with javascript, and I came upon a site, on the site you have to try to figure out the passwords which are embedded in javascript, now im on the last level but i have no clue whats going. It seems to be an undefined variable. Can anyone point me in the right direction? Code:
Does anyone know why the onclick in the following popup menu gives the error:"Val is undefined"? Does it have something to do with the fact that it is called within the variable tablePop? Because it IS displayed properly as part of the popup text, where it is called outside the single quotation marks (see [***]). It is only in the onclick that it's causing problems. Code:
When I click my button, window.frames['akFrame'].document.getElementsByName('auth_key').value is undefined, and I cant seem to make the if else statement work.
The value of startTime when called from display() is undefined. I'm not sure why, as I declared the variable outside the function. The variable should be accessible by all functions, right?
I am trying to write a snippet to put in my form and cannot get it to run. I keep getting an undefined error for the variable 'Code' no matter what I do.The goal is present obtain a Time Frame based on an SVCode selected from a group of radio buttons.
We are currently re-working a client's website and as I am not a javascript programmer I am having trouble understanding some of the code, and need help understanding why a certain variable in the code remains undefined.
What is happening is that the user is filling in 24 lines of 4 select boxes, in which there must be 1 and only one "m" and 1 and only 1 "l". The code changes the value of the box back to blank if the user has tried to enter >1 of either. The code then should check the line number and count the number of lines, but on debugging I see that the value of variables el and LineNo are undefined. I can't understand why when the function is called, the value "this" is used. i.e CheckLine(this) - this appears to have no value in the html code as far as I can see!
I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code***************************************** //new ajax already created and assigned to the variable xmlhttp// var response_recieved = "some data"; function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.
I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.
I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.
I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.
I am trying to access the width variable from my main page. Within the imageinfo.js script functions I can alert() the width value which returns 1024. But I can't seem to pass this variable to my main page or access it directly so that I can use document.write() to write the variable on the page. Whenever I try to call the 'width' variable directly from the main page I get undefined. How can I access this variable? However, with the test code below, I was able to get ducument.write() to write the 'width' variable on the page but now the page doesn't stop loading - there's an endless loop in the code...
[code] Hide from browsers that do not understand Javascript.The addLoadEvent function adds functions to the window.onload command to load multiple functions at startup function addLoadEvent(func)[code]When the page loads I get the nice alert box that says loading and then one that says count equals 0.When i click my edit list drop down and choose modify I get a message box that reads count equals in edit function 0.If I type text in the textbox and leave the text box I get an alert box that reads count equals in subcheck function Undefined and then another one that says NaN.
I've written a function to format a number. It strips dollar signs and commas, converts to a number, and sets the number to two decimal places.However, I get the error message "amountNum is undefined". It occurs right where I use the replace command.[code]I am calling the function with this line of code:[code]
I am pretty new to Javascript having a bit of a problem with a website with Google Maps integrated. URL I have two checkboxes (ccCheck and caccCheck). The basis is when the box is ticked, it overlays a KML onto the map. This is working fine in Chrome, but in FF and IE it doesn't work, IE returns 'ccCheck is Undefined'. The code I am using is in the JS file, the bit it gets stuck at is as follows:
[Code]...
If I stick a ccCheck = document.getElementById('ccCheck') within the onclick function (before the if statement), it places the overlay onto the map, but then when I untick the box it just stays there. It's such a simple thing (I think), and must be down to IE being pedantic about declaring the variable properly, the question is how should I be doing this?
