I'm trying to replace each digit of a 4 digit integer by( the sum of that digit plus 7) modulus 10. And then swap the first and third digits and swap the second and fourth digits.this is what i have come up with so far and I cannot get it work.
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
I have a long paragraph which contains almost 2000 words.I want to extract all those words or group of words which are in single quote e.g.In the below sentence, I want to extract 1. is 2. important and 3. topic.This 'is' very 'important' 'topic' to discuss.Any body have any idea how to do this in javascript.

I need to make script which takes from one field string(numbers separated by space copied from excel) divide it by space into variables and insert into another fields on this page. <textarea name="receiver1" id="receiver1">
How do I extract "somestring" only? I'm on IE7. <script type="text/javascript"> var x = "(EVAL)(H:somestring)Some other Text here"; var full =(x.match(/(H:(.*?))/g)); // produces "(H:somestring)" as expected alert(full); var inside = (x.match(/(H:(.*))/)); // produces "(H:somestring),somestring" .. I only want "somestring" alert(inside); </script>
I had a difficult time figuring out how to get or test the last character of a string with javascript.
I found plenty of removing the last character, but not for just checking what the last character of a string is using javascript.
// create string var str = new String("No Periods Allowed."); // alternatively get string from field: // var str = document.getElementById('textbox').value;
[Code]....
Well, finding that easily on a search would have saved me some time.
I want to insert a character into a string. Whats the best way of doing this? So if I want to insert a hyphen(-) into the string 'oneway' giving me 'one-way'.
The last line in this JS function should remove the final comma from the end of the given string... but for some reason, it does not.Instead of returning something like:
This string is a key in our database that I have no control over and I want to set the value of the menu according to this value because it is unique. I suspect that the '' or the '>' or the '!' is making Javascript think that this is a different type of data than string.
Is there a way to 'force' Javascript to interpret this as string?
I have a form with a textarea field. I want to validate the input from the textarea using javascript. Suppose I want to check that the user has not entered the string: "Hello World!"
To do this I am using the script: form["text"].value == "Hello World"
But this gives an "unterminated string constant error" because the browser converts this to: form["text"].value == "Hello World"
I am trying to split out a string. E.G "Australia - VIC". I want to remove everything before the -. The line of code I am using to do this is: var state = optionText.replace(/.* - /,""); This works in IE7, but in all other browsers is only removing the - resulting in "Australia VIC" rather than the desired "VIC"
what character occurs most frequently in a textarea. Do I really have to store every single character in an array and then sort it? Is there a Regular Expression for this?
I've got the following form validation script. How can I include the quote marks as a bad character?
I tried: var bad_email_chars="/!#$%&*+^ ()_-=|~`?;:,'""" It didn't help.
if(form1.elements(i).name=="text_website") { var bad_email_chars="/!#$%&*+^ ()_-=|~`?;:,'" var h,j for(h=0;h<bad_email_chars.length;h++) { for(j=0;j<input_str.length;j++) { if(bad_email_chars.charAt(h)==input_str.charAt(j)) { alert("you have atleast one bad character in you website address. You may not submit this form until you correct this.") window.event.returnValue=false form1.elements(i).focus(); }}}}
Also, How do I format with indentations and as non wraping text the messages I send to this forum?
