I am creating a little html editor, and I want to highlight a chunk of
unformatted text, click a <buttonand put a <pand the beginning and
a </pat the end. I assume there is a DOM element relating to this,
can anybody help please ?
It needs to allow the user to highlight some text within a paragraph. If the correct text (with an error) is selected it should provide feedback that the user has correctly selected this text.
So what I need to do is
1. Get the text selection
2. Compare this text selection to a predefined answer
3. Provide feedback to the user e.g. they are correct if text selection = predefined answer, and incorrect if text selection != predefined answer
I am wondering if it is at all possible to create a button that--when
clicked--grabs a paragraph of text that a user has highlighted. So you
go to this website, then highlight a section of text. Once you have
the text selected with you mouse, you then click the button. The
button executes a function which acquires the selected text in a
string. Is this hypothetical situation possible? Thank you for the
time it took to read this post.
Is there a way of searching for highlighted words on a webpage?
View 4 Replies View RelatedI am a JS newbie and I'm wondering if there a way to figure out the sentence from which a word has been highlighted. Essentially, when a user selects a word or a phrase, I should output the sentence from which it's been selected. Is this possible with JS or with any server side languages?

I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I have a JS function which checks whether the directory field value entered starts with an alphabet or number only. Following is the code using regular expression.

I have to do something that looks an easy task, but I can't do it.I have a page with a div and an id= "livetimings" assigned to it, I want to show a table inside that div and update it every 20 seconds.I have a php script which prints the table and it works, I've tried that script by itself, now I'm trying to call it through an AJAX call in this way [code]inside the <body> tag I've put a setInterval() which starts the getTempi() every 20 seconds and it also works.The not working part is that nothing appears inside the div.I've put some alerts inside the JS code all of them before the req.open pop up, then nothing, so I think the problem is there, but I don't get it.script.php is in the same folder of the html page.The php script has an echo at the end which prints the html code for the table.
View 2 Replies View RelatedI wanted to only match in the middle of a string
I have a string = " sdfasf 23234"
I wanted to get the numbers like /([0-9]*)/
But this fails and returns nothing because the string begins with letters. Instead I had to do /[a-zA-Z ]*([0-9]*)/
If that's the case then, why do we bother with something like
/^[a-zA-Z]*([0-9]*)$/
The pattern is already assumed to start at the beginning of the string
Is there way to only match on strings starting with the first characters input?For instance, if I have a list as such:[ 'Tamara','Amy']when I start to type 'Am', I only want to see "Amy" in the drop down list, not "Tamara".I feel like this should be an easy configuration option or easy mod, but alas, I could not find it.

I'm trying to accomplish the following, preferably using jQuery, find this string on a page (it occurs only once).. 'BC-' and then, depending on the page i'm on either - add a simple <br/> tag before it, or enclose in it within a span tag with a class. adding the span would be more complicated because 3 numbers follow the BC- ex: BC-103.
View 5 Replies View RelatedI require to highlight the text on the webpage. For that I am using document.getSelection() function to get the selected text and then replace the text with the highlighted text. It works fine but have some problem with that.
If user has selected a single word rather then a long text to highlight, and if it's a common word, It will find many words in the text and will highlight the first word it encounters no matter user has selected it or not.
So I need to have a function that returns me the start and end index of the selected text from the html text.
Is it possible to create a function that will find a class name or id name and then assign that name as variable string?
For example, my body has a class name:

Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string

Unfortunately that doesn't work. I understand that the index() isdocumentation (though confusing) correctly tells you that the above code doesn't work. Maybe I'm just weird, but I feel that the way .index() is implemented for string arguments is very counter intuitive. I have an expectation that .index() is similar to indexOf() in javascript.
