To use a special character as a regular one, prepend it with a backslash: \. . That's also called “escaping a character”.
To check if a string contains special characters, call the test() method on a regular expression that matches any special character. The test method will return true if the string contains at least 1 special character and false otherwise.
I am trying to include some symbols into a div using JavaScript.
It should look like this:
x ∈ ℝ
, but all I get is: x ∈ ℝ.
var div=document.getElementById("text");
var textnode = document.createTextNode("x ∈ ℝ");
div.appendChild(textnode); <div id="text"></div>I had tried document.getElementById("something").innerHTML="x ∈ ℝ" and it worked, so I have no clue why createTextNode method did not.
What should I do in order to output the right thing?
