Logic Error On Limiting The Modification To The Maxvalue ?
Feb 26, 2011
How to create a function that would allow me to add to or subtract from a maxvalue, and thankfully I got help regarding that. However, something's got me stumped for the past few weeks that I still can't resolve...
This is the relevant code:
As it stands, it works as long as the total value is less than or equal to the limit (for advantages it's 15, for disadvantages it's 10). However, the moment it goes past the limit -- for instance, if you change Antisocial's value from 2 to 7, or if you add several additional checkboxes with any values -- the whole thing starts going crazy; specifically, maxvalue doesn't revert to 40 when the all the checkboxes are unchecked.
What I'd want to happen is that the user cannot select or apply advantages or disadvantages if the maximum advantage is greater than 15 or the maximum disadvantages is greater than 10.
I'm thinking that a button for adding disadvantage points to/subtracting advantage points from the maxvalue (that becomes disabled if the user goes past his limit on advantages/disadvantages) is useful at this point, but I'm really stumped on the implementation of the idea. An alternate idea of mine is that all other advantage/disadvantage checkboxes would become disabled if their value is greater than the remaining number of points, but I don't know how that is possible either.
Putting some javascript into a pdf file and can't get this to work out right.
Basic setup:
Field X = checkbox; Field Y = numeric input field;
Here's what should happen (increment is toggled):
Y has a value. When X is checked, Y is increased by 5. When X is unchecked, Y goes back to its original, unmodified value.
Here's what really happens (increment is subtracted):
Y has a value. When X is checked, Y is reduced by 5. When X is unchecked, Y is reduced by 5 again. Anytime X is clicked on, Y is reduced by 5 yet again.
I am using the treemenu from here [url] It works great, but my clients wants to have the functionality that (if there was only two levels) that if you expand into one level and view all the sub items and then click on the another main node that it would contract all existing items and then display the new sub node?
How can I change the behavior of the alarm clock script from Javascript Kit located here [url] to make it so that it displays a simple alert message instead of following a link?
I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?
I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.
The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.
Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.
I needed to calculate my prices on-the-fly and display it in textbox with javascript. Well I did succeed with values of radio button an checbox, but as I know very little javascript, I don't know how to expand the code I got from here: [URL].
How can I make this happen: I have a textbox: HTML Code: <input type="text" name="podstranice" size="19" class="podstr" onkeyup="this.form.total.value=calculateTotal(this);"> And when a user inputs a number in it, javascript multiplies it with some other number, say 10 (its a price*quantity thing) and adds it to the total price along with data from checkboxes and radio buttons. And so, this is my javascript. It is basically identical to one on the link, but you can view it better this way I think.
Code: // Calculate the total for items in the form which are selected. function calculateTotal(inputItem) { with (inputItem.form) { // Process each of the different input types in the form. if (inputItem.type == "radio") { // Process radio buttons .....
Is it possible to make it so that image that is displayed in the div is limited to certain dimensions.. say 100 by 100px. If an image that is displayed is above the limit, the excess is simply just out of view..
I dunno how this would be possible maybe by a use of some sort of mask, i normally code inflash im not sure if taht is possible with divs in html. Or maybe you can limit the size in the js file, if your allowed to.
I have been looking into the following lightweight image gallery:[URL]... It does everything I want except for displaying thumbnail images (it crops the original images). Some dude has posted details as to how this may be done, but I am baffled as to why it will not work. Here is the javascript:
I have a input filed of type "textbox" into which I am expecting to get currency values (ie. 199.99). Is there a way that I can restrict the user to only entering 2 values after the decimal point?
I can restrict the maxlength to 5, but that wouldn't stop the user from type in 1.987.
Which grabs all "li" tags with the ID "friends" , and then goes through and clicks all of those elements.How would I go about having it to where it only clicks up to 200 elements, and not all of them.
im trying to set a textbox to only accept alphanumeric characters but it needs to accept a space in between each entry because it is a textbox all i can get it to do now is only allow numbers to be entered using the following code:
I'm adding title attribute to some elements by using mouseenter function. But I would like to hide the shadow which comes by default nehind the tooltip frame and wrap the text in 2 lines!
[URL]. I looked at this script and I tried playing around with it but could not figure out how to: Instead of having a check box field and then a radio box field, have 2 radio box fields, so the user picks from one group of radio boxes and then another. Then change the math behind it so the values in the first field are multiplied by 100 and then the values in the second field tack on a percentage (ex value in first field is 1.5 so 1.5x100 = 150 and value in second field is .5 so total is 225).
its possible to limit variables example I have a variable called myCurrency containing 3.454 well sort of pass it to a function that makes it become 3.45 though if the third number is higher than 5 it rounds it.
I am no coder, however I am modifying my website and changing the slideshow to the one found on this website, most wonderful, the Cut & Paste JavaScript Slideshow : [url]
I have it working now, and I have but one question, does the code include a way to limit the number of times that it cycles through the slides? So it just freezes on one photo after x number of cycles?
Is it possible to use javascript to limit a textarea to one hundred words (of 3 or more letters).
I am building a contest form for my company. It's one of those that you have to write why you want to do something in 100 words or less. I would like to have it check their writing while they're writing. It would be really cool to tell them how many words they've used.
I've seen javascripts that tell you how many letters in a given field. Something like that would be perfect. Does anyone have something like that or can you point me in the right direction?
I'm trying to limit the number of items that can be passed to the 'list1' select box to ten items. The way I have it now, it pops up a warning if user tries to pass more than ten, but then passes the first ten of the selected items through to list1 anyway. I don't want it to pass any items if they try to pass more than ten...just show the popup, and make them try again. Code:
I use the following code to add a "click" behaviour to an element:
$(document).ready(function(){ $("#element_id").click (function(){ ...... do something ....
[Code]....
Part of the node I clone is the element from the first piece of code I quoted. The addRowJob function also changed the ID of every element in the node I cloned. This way all IDs remain unique. Lets say the element in question has the ID "#element_id". Now I clone the node (which includes the element) and the cloned element gets its ID changed to "#element_id_new".
Of course I now want this newly append element ("#element_id_new") to have a click event attached to, but even if extend my $(document).ready(function() to:
$(document).ready(function(){ $("#element_id").click (function(){ ...... do something .... });
[Code].....
I simply doesn't work for the appended element.
My guess is that the $(document).ready(function(){ only fires when the document is finished loading. At this stage there is no element with the ID "#element_id_new" and therefore the click event can't be attached to the element. Makes senses...
But how do I get this click event attached to the newly appended element with the ID "#element_id_new"?
I have writting all of my paging logic in javascript. It works pretty fine. Basically, I have created a gridview with full paging in javascript. Now, given a certain need, I am being advised to do my paging on the server.
My question: is there a performance cost by doing all my paging server-side (and cost benefit by keeping it on the client). Or, does it matter?
I want to create an image gallery like imageflow, but having tough time to figure out the way top, left, height and width are computed for each animation call.
I have been successfully using the following "myAjax" function to load text file information from the server.
ajax.js:
After I load the text file, I store the text "records" into an array by doing something like this:
Where the '}' character is my record delimiter. It could just as easily be ' ' or ' ' or the like.
Again, I am not having any problems doing it this way as it suits my current needs.
Now the question(s)
1. Does the call to read the text data from the external file always read in the entire contents or can I read one line or delimited record at a time and store it to the array directly without the text storage?
2. If the text is always read completely (my suspicion), can I safely delete the "TextInformation" after I convert to the array format? Is there any memory penalty for doing it this way as the text information can be somewhat lengthly and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?
This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.
