By using (x|y)
expression we can find any of the specified alternatives.
<p>Click the below button to find any specified between the brackets.</p> <input type="button" value="Click" onclick="mySearch()" /> <p id="myId"></p> <script> function mySearch() { var a = "Tec, TechFunda, ITFunda, TechFunda, ITFun, NetFun, TechFunda, ITFunda, DotNet"; var b = /(TechFunda|ITFunda)/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>
block which is connected to the onclick of the HTML button and there is a string with value "Tec, TechFunda, ITFunda, TechFunda, ITFun, NetFun, TechFunda, ITFunda, DotNet" to the variable a
, from the string we need to find the specified alternatives by using (x|y)
expression in variable b
. Variable r
returns the specified alternatives between brackets from a string. Onclick of the button "Click" in the HTML code fires the function mySearch() in the <script>
block, at the same time (x|y)
expression finds the specified alternatives between the brackets {(TechFunda|ITFunda)} from a string with the help of global search and returns the output.
