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 have a survey with hundred of input boxes. I want to make a script that will validate all fields not empty and maybe jump to the empty box. I made the validation with php but i'm not so good at javascript (if is possible to validate by input not by input name).
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 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:
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?
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:
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.
How would i change back to the default length of textarea?
I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...
EXAMPLE:
The problem is that the textareawon't change back to it's default size // let's say that the default size is rows=3
I have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.
Now i got a function newgame() and i wanna display random word from this array in rectangles gray styled... Here is the problem. I can make to display random words, but i dont know how i make this words with the css style together - rectangels around a char. But the words are different length so i dunno?
I am in position to get the no. of lines in a 'div' and the words in each line inside a div tag. Is this possible to achieve using jquery. I have googled for so many hours but could not find any results related to my requirement.
