I want to get number that is stored in a tag like
var x="<a>1234</a>";
using JavaScript. How can I parse this tag to extract the numbers?
Parse the HTML and get value from the tag.
There are 2 methods :
var x="<a>1234</a>"; var parser = new DOMParser(); var doc = parser.parseFromString(x, "text/html"); console.log(doc.querySelector('a').innerHTML)
var x = "<a>1234</a>"; // create a dummy element and set content var div = document.createElement('div'); div.innerHTML = x; console.log(div.querySelector('a').innerHTML)
Or using regex(not prefered but in simple html you can use) :
var x = "<a>1234</a>"; console.log(x.match(/<a>(.*)<\\/a>/)[1]) console.log(x.match(/\\d+/)[0])
var x = "<a>1234</a>";
var tagValue = x.match(/<a>(.*?)<\/a>/i)[1];
console.log(tagValue);
it is by Regular Expression, assume x hold the value of the parsed html string:
var x="<a>1234</a>".replace(/\\D/g, ""); alert(x);
should work
