I have a string like that
const str = "<p><p><br></p>something</p>";
I want to check if the string has one or more char without <, >, p, /, b, r, (whitespace)
. In the above case it should true, because the string has char of s, o, m, e
etc
How can do this check ?
You can extract the text from html and check like below:
function extractContent(s) { var span = document.createElement('span'); span.innerHTML = s; return span.textContent || span.innerText; }; cont = extractContent("<p><p><br></p>something</p>"); if(cont) console.log(cont, true)
You could use lookaround in regex.
Lookahead and lookbehind, collectively called “lookaround”, are zero-length assertions just like the start and end of line, and start and end of word anchors.
Example.
let regex = /(?<!<)[\\w](?!>)/g; const str = "<p><p><br></p>something</p>"; if(regex.test(str)) { console.log('Yes'); } else { console.log('No'); } console.log('Match: ', str.match(regex).toString());
OR just use simple Character ranges
.
let regex = /[^pbr<>\\/]/g; const str = "<p><p><br></p>something</p>"; if(regex.test(str)) { console.log('Yes'); } else { console.log('No'); } console.log("Match: ", str.match(regex).toString());
I just figure out with lodash's pullAllBy
function
let arr = "<p><p><br></p>somebbthing</p>"
const s1 = arr.split('');
let newArr = _.pullAllBy(s1, ['<', '>', '/', 'p', 'b', 'r']);
if(newArr.length > 0) {
console.log('true');
}
