Global search is an search in JavaScript, which can be done by using regular expression g modifier.
Regular expression is nothing but an object which describes a pttern of characters.
<p>Click the below button to do case global seacrh.</p> <input type="button" value="Click" onclick="mySearch()" /> <p id="myId"></p> <script> function mySearch() { var a = "TechFunda is a sister concern of DotNetFunda"; var b = /Fun/g; var r = a.match(b); document.getElementById("myId").innerHTML = r; } </script>
In the above code snippet we have given Id as "myId "to the second <p>
element in the HTML code. There is a function mySearch() in the script code which is connected to the Onclick of the HTML button.
A string with value "TechFunda is a sister concern of DotNetFunda" to the variable a
, from the string we need to do a global search for a character 'Fun' in a string, for that we are using g modifier in the variable b
, variable r
returns the global search result.
Onclick of the button "Click" in the HTML page fires the function mySearch() in the script code, at the same time g modifier do the global search for a character 'Fun' in a string and returns the output.
