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.
I 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 many divs with spans inside(just like it is below-no extra ids,classes for spans: [...] <div> <span style="color:red;">a</span> <span style="color:blue;">b</span> <span style="color:white;">c</span> </div> <div> <span style="color:red;">d</span> <span style="color:blue;">a</span> <span style="color:white;">a</span> </div> [...]
What I would like to achieve: user selects with mouse "ab", click button(input type=button) which remove style from selected span/spans. Similar behavior like it is in TinyMCE.
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.
I 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.
below is my code and i cant seem to figure out how i can loop the string and find the location of letter "a" in the string and display it like "1 3 17" ... i cant seem to figure out what i am doing wrong in the loop and keep getting "1 1" ... Thanks before hand!
i know you'd do a search with a regular expression, but i can't find the correct one on the web...even though i know there has to be a billion examples out there. my google search skills are s#&@ today. code...
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.
I 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.
I'm trying to learn jQuery and am currently attempting to clone a div and then find and replace part of a string. The cloning part works, but I can't seem to get it to alter the text... In the html below, I'm trying to find all instances of issue-0, issue_0, or issue (whether it's a name or an ID) and replace it with issue-1, issue_1, or issue (depending on the character found after "issue")
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
find a char sequence in a string and highlight that with red color.
In text box when they start typing i will get list of string matching in a div. for example when they start typing "A", i will get a result as Atlantic Alaska Atlanta, some thing like this. high light "A" in all the String of the list to red color, in the same way when they type "AT", then "AT" in red color.
