only have test one browser - Mozilla - but have the impression, that newlines when setting innerHTML doesn't go down very well with the browser. Is this sufficient for causing a hard crash or at least an exception? Can anyone verify that? (Just a guess now at the moment)
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
I have a form with a textarea field. I want to validate the input from the textarea using javascript. Suppose I want to check that the user has not entered the string: "Hello World!"
To do this I am using the script: form["text"].value == "Hello World"
But this gives an "unterminated string constant error" because the browser converts this to: form["text"].value == "Hello World"
I am trying to change the font color of each character of the innerHTML of a div. I have tried the following but obviously I have not gotten it to work.
This is just a snapshot of the javascript which I have that "changes the color and size of the characters..
Code:
function change() { var r = 0; var len = document.getElementById("userInput").value.length;
I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen() { var iChars = "`<>"; for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
In my application (yes I know that it's asp) I need to automatically replace a character if it is found in the textbox Is there a way to do this. this is how it renders on the page
I am trying to replace new line character with the <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
I am trying to retrieved the value of the textarea with the newline preserved without having to submit the form to the server. Does anyone knows how to? I tried soft and hard wrap but both does not seems to affect the input in anyway.
Example : <form name=frm> <textarea name=ta wrap="soft"></textarea> </form> <script language=javascript> alert(document.frm.ta.value) // <-- the alerted value should look exactly as what is entered in the textbox. </script>
I am trying to replace all newline characters with <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
This of course print each word on a new line in the browser. The problem is when the user copies and pastes the text, it appears as one long string of text with no breaks. Now consider the following script:
In textareas or input textboxes, when you dynamically add ' ' to the textbox's value, is it automatically converted to ' '? If it does, in what browsers does this happen? Firefox (and other Geckos)? Opera? Konqueror?
my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]
I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.
Does anyone know the escape character for & and # like in : Update GDO_INFO_ER set V_COMMENTAIRE='B&A' where V_USERMODIFICATION='bilal123' or Update GDO_INFO_ER set V_COMMENTAIRE='B#A' where V_USERMODIFICATION='bilal123' I would like to insert & and # literally in the table.
But when I mouse-over the link, the %27 shows in the status bar as a ' and when I click on it, I get a JS error because of the extraneous '. The +s are not being decoded - why is this one character, and is there a way to prevent it?
I have this string: "60 105 109 103 32 115 114 99 61 34 101 108 111 46 106 112 103 34 62", and I'd like to convert it to the characters. I've used the split method to separate it but I don't know how to transform each number in the character. Could you hel me?
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 have a little problem with the follwoing JS, when i count characters for Input type text the reult is ok but when i am using textArea it says 'NAN' here is my code,
--------------------------------------- <script language = "Javascript">
function taLimit() { var taObj=event.srcElement; if (taObj.value.length==taObj.maxLength*1) return false; }
function taCount( taObj ) { var lbObj=document.getElementById("myC"); if (taObj.value.length>(taObj.maxLength*1)) { taObj.value=taObj.value.substring(0,(taObj.maxLength*1)) }; var count; count = taObj.maxLength-taObj.value.length; lbObj.innerHTML=parseInt(count);
I was wondering if there was any easy way to do the following in javascript:
I have two form fields, firstname and last name, as the user enters their information into a form I want to be able to show them what their username is going to be.
While they enter the information into the fields I was hoping to have it generate the username as the type.
I need to take the first letter of their first name (the first letter in the firstname field) and the entire lastname to combine it into a username. Except if there are spaces or any other characters such as dashes apostrophes they must be removed.
