I want to remove the spaces at the end of the class attribute in this string:
<div class="test wrapper " id="test"> " sample text " </div>
If I use
text = text.replace(/\s+"/g, '"');
then the space after sample text also will be removed and I want to keep that space.
Do you have any idea how can I do this?
Make your regex more specific
By adding class=" to your regular expression, you can narrow the scope of the replacement. Then using a capturing group () and the $n replacement pattern, you can save just the list of class names excluding any spaces:
var text = '<div class="test wrapper " id="test"> " sample test " </div>';
text = text.replace(/class="\s*(.+?)\s*"/g, 'class="$1"');
alert(text);
if you want result which looks like
"sample test"
then use this code
with js:
var str = " sample test "; var newStr = str.trim(); //
"sample test"
and with js and regular expression:
use this code:
var str = " sample test "; var newStr =
str.replace(/(^\s+|\s+$)/g,''); // "sample test"

Im trying to save some HTML in a JS variable by using the backtick formatting however is it possible to preserve the HTML variable according to the following example
var msg = "This is a test" + "\n" + "Test"
Im attempting to store this variable as a HTML paragraph while keeping the linebreaks
var emsg = '<p style="white-space: pre-wrap;"><\"{msg}"\</p>'
But when sending that content in an email to myself (Using Emailjs) I get the following
<"{msg}"
Any clue what I'm doing wrong? Thanks!
You are using single quotes ('), not backticks (`)
Placeholders in template literals are indicated by a dollar sign ($), which you are missing.
var msg = "This is a test" + "\n" + "Test"
var emsg = `<p style="white-space: pre-wrap;"><\"${msg}"\</p>`
console.log(emsg)
You could go with template literals like #spectric showed.
or you can go with simple quote using + to seperate it with msg variable
var msg = "This is a test" + "\n" + "Test";// V V
var emsg = '<p style="white-space: pre-wrap;"><\"'+msg+'"\</p>';
console.log(emsg);
as described + removing the extra <\" and "\ probably
var emsg = <p style="white-space: pre-wrap;">${msg}</p>
I have a paragraph which has HTML tags in it. I need to restrict it to 100 characters after the parse of HTML. For example
Hello World
If my length check is for 8, then my HTML should be Hello Wo where Wo should be an anchor tag. There can be any other tags. Any help would be appreciated.
You can use a REGEX expresion when getting the innerHTML
Then count the characters.
Example:
var regex = /(<([^>]+)>)/ig;
var body = 'Hello World ';
var result = body.replace(regex, "");
console.log(result + ' ' + result.length);
$(document).ready(function(){
var $html=$('<span></span>');
$html.append('Hello World ');
var text=$html.text();
console.log("Text :: "+text);
console.log("Length :: "+text.length);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Using this way you can create html elment virtually then text() will parse the text content from html.
Hi I am having the string which contains html content and I want use javascript to replace the tag <p class="MsoNormal"> with '' empty space and i want to replace corresponding closing tag </p> with <br> tag in that string.
If I use
first line:
str=str.replace(/<p class=\"MsoNormal\">/g,'');
second line: str=str.replace(/<\/p>/g,'<br>');
All the closing </p> tag get remove .But i want to replace the closing </p> tag which has the opening tag of "<p class="MsoNormal">".
The first line of script is okay of me .What should i use to replace that corresponding closing tag in the second line.
Check this: Output is what I got from your question is to replace with Empty String
var replaceTag = function(str, replaceTagString, endTagString) {
var str = '';
while(str.indexOf(replaceTagString) != -1) {
//search for </p> after my matched String
var indexOfClosingTag = str.indexOf(endTagString, str.indexOf(replaceTagString))
//Replace </p> using Substring
str = str.substr(0,indexOfClosingTag) + "<br>" + str.substr(indexOfClosingTag + endTagString.length,k.length)
//Replace your main String
str = str.replace(replaceTagString,'')
}
return str
}
var k = "<p class='MsoNormal'>something</p><p>other p tag</p><h1>I am h1</h1><p>Hello p</p><p class='MsoNormal'>Replace My Tag too</p>"
replaceTag(k, "<p class='MsoNormal'>", "</p>")
Output:
"something<p>other p tag</p><h1>I am h1</h1><p>Hello p</p>Replace My Tag too"
Concept:
string.indexOf(searchvalue,start)
Start searching for End of the Tag (P) after my current matched string position
Define a function yourself like this-->
String.prototype.replaceAt=function(index, character) {
return this.substr(0, index) + character + this.substr(index+character.length);
}
And use it like this:
str = str.replaceAt(3, "</p>");
why won't the cursor enter some of my divs when contenteditable is enabled?
also, why does my browser tell me there is nothing in the div when there is clearly a space character in it?!
var div = '<div> </div>';
div.innerHTML = undefined
What gives?
contenteditable does not apply to empty elements, so you may want to insert a non-breaking-space character into the empty elements you want to be able to edit
the non-breaking-space " " will act as a character when left on its own,
whereas a whitespace " " will only count as a character if placed after another character
<div>" "</div> ----------------> innerHTML = undefined
<div>" "</div> --------> innerHTML =
the gray box around means its an html character
so make sure you insert a " " and not a " "
var nbsp = " ",
div = document.getElementById('id');
div.innerHTML = nbsp
jquery works too
var div = $('div#id')
div.html(nbsp1)
I'm trying to fix an inline javascript snippet with reg ex to be rewritten on an input field.
I have single quotes that wrap the inner double quotes and I want to convert the inner quotes to be single instead of double but I only want to convert them when the code appears as nested quotes.
Right now I'm doing the conversion for all instances of the quote which works but I might run into another problem. I'll attach my code below.
JavaScript
$(document).ready(function() {
$('.submit').bind('click', function(e) {
var yourstring = $("textarea").val();
yourstring = yourstring.replace(/'/g, "''");
yourstring = yourstring.replace(/"e;/g, "\"");
yourstring = yourstring.replace(/&lquote;/g, "\"");
yourstring = yourstring.replace(/&rquote;/g, "\"");
yourstring = yourstring.replace(/"/g, "\"");
yourstring = yourstring.replace(/“/g, "\"");
yourstring = yourstring.replace(/”/g, "\"");
yourstring = yourstring.replace(/"/g, "\"");
alert(yourstring)
});
});
HTML
<textarea style="width:400px;height:300px;">
function('');
<a onclick="$(".text").append('test');">Click Me</a>
<br/>
&lquote;test quotes&rquote;
" generic quotes "
</textarea>
<input type="submit" class="submit">
To be more specific I'm trying to get
<a onclick="$(".text").append('test');">Click Me</a>
To look like
<a onclick="$('.text').append('test');">Click Me</a>
The example provided does not seem to have anything to do with the database but a problem with the JavaScript code within the onclick attribute. That code actually doesn't have a valid syntax, but my guess is that you are trying to build some sort of editor for HTML code.
If you decide not to follow the recommendations in the comments above (which I agree with), to answer your question, here's an option for removing double quotes for text already surrounded by them:
var s = "<a onclick=\"$(\".text\").append('test');\">Click Me</a>";
var re = /"(.*)"/g;
var r = s.replace(re, function($0, $1) { return '"' + $1.replace(/"/g, "''") + '"'; });
console.log(r);
