How do you replace a certain part of a string JavaScript?

var textDiv = document.createElement("div");
textDiv.innerHTML = data[i].text.replace(pattern, "");

Live example:

If you don't want to use markup, you can append the part of the string before the {0}, then the element, then the part of the string after the {0}:

var select = document.createElement("select"),
    textDiv = document.createElement("div"),
    text = data[i].text,
    index = text.indexOf("{0}"); // No need for case-insensitivity
if (index === -1) {
    index = text.length;
}
textDiv.innerHTML = text.substring(0, index);
textDiv.appendChild(select);
if (index < text.length) {
    textDiv.insertAdjacentHTML("beforeend", text.substring(index + 3));
}

Or if the pattern has to be a regex:

var select = document.createElement("select"),
    textDiv = document.createElement("div"),
    text = data[i].text,
    match = pattern.exec(text),
    index = match ? match.index : text.length;
textDiv.innerHTML = text.substring(0, index);
textDiv.appendChild(select);
if (match) {
    textDiv.insertAdjacentHTML("beforeend", text.substring(index + match[0].length));
}

Definition and Usage

The replace() method searches a string for a value or a regular expression.

The replace() method returns a new string with the value(s) replaced.

The replace() method does not change the original string.

Note

If you replace a value, only the first instance will be replaced. To replace all instances, use a regular expression with the g modifier set.

Browser Support

replace() is an ECMAScript1 (ES1) feature.

ES1 (JavaScript 1997) is fully supported in all browsers:


Chrome	IE	Edge	Firefox	Safari	Opera
Yes	Yes	Yes	Yes	Yes	Yes

The JavaScript replace() method is used to replace any occurrence of a character in a string or the entire string. It searches for a string corresponding to either a particular value or regular expression and returns a new string with the modified values.

One can also use regular expressions instead of strings for defining the character or string to be replaced. A regular expression is a string that contains special symbols and characters to find and extract the information needed from the given data. Regular expressions are basically strings containing characters and special symbols that can help to select the required values.

One has to note that the replace() function will replace only the first occurrence of the specified value. In order to replace all occurrences, one has to use the global modifier.

Syntax:

string.replace(valueToBeReplaced, newValue)

where ‘valueToBeReplaced’ can either be a string value or a regular expression.

Example 1: The replace() function will be used to replace the string ‘Hello’ with ‘Hi’

html

<html>

<head>

<title>Replace Exampletitle>

head>

<body>

<h2>Hello welcome to our blog!h2>

<p>

// in the page with "Hi"

function rep() {

document.body.innerHTML

= document.body.innerHTML

.replace("Hello", "Hi");

}

script>

body>

html>


Output:
Before clicking the button:
 
After clicking the button:
 
As seen in the above output, only the first occurrence of ‘Hello’ was substituted with ‘Hi’. To substitute all
occurrences, a global modifier has to be used.
Example 2: Use the replace() function to replace all occurrences of the string ‘Hello’ with ‘Hi’
html

        // in the page with "Hi"
        function rep() {
            document.body.innerHTML =
                document.body.innerHTML
                .replace(/Hello/g, "Hi");
        }
    script>
body>
html>

Output:
Before clicking the button:
After clicking the button:
 
In the next example, both the global modifier and “i” modifier are used to ensure that all occurrences of the given word
are replaced irrespective of their case.
