Jquery If Else for Beginners

jQuery is a JavaScript library that provides DOM manipulation, event handling, animation effects, and Ajax capabilities. Jquery if else allows you to create conditional statements that execute different codes based on the outcome of its condition. In this blog post, we will cover how jquery if else works in the jquery programming language and provide some examples so you can get started using jquery if-else for yourself!

Jquery if else:

jQuery if-else is a javascript statement that allows you to create conditionals for the execution of jquery code. jQuery if-else provides the benefit of being able to run different jquery codes based on the input in order to meet any jquery requirements. The syntax for jquery if-else would be:

Syntax:

if($("#element")){

//do something here!

}else{

//do something else here!

}

Example:

 var	a = 5,
	b = 10;

if(a > b) {
	$("body").html("A is larger than B");
}
else(a == b) {
	$("body").html("A is equal to B");
}

In jquery, there is no if-else statement available. jQuery is the javascript’s library so jQuery can be used all the features that are available in javascript. So don’t be confused.

What is the If else statement:

If-else is a conditional statement that allows you to create conditions for the execution of code. In every language, the syntax is the same as above.

There are few kinds of conditional statements available:

If condition:

There are many occasions when you might want to execute a specific block of code only if some condition is met. For example, imagine that we have an array with the values 1, 2, and 4 stored in it:

When we check whether this particular value exists within our array using “if”, which checks for equality (==), the following will be run on both lines:

var i = 0; 

if(i == 3) 

{ //do something} 

else

{ console.log("No match found"); 

If-else condition:

You can use else if to specify new conditions in case the first condition is false. For example, assume you have a list of numbers that are either even or odd and want to know how many are greater than 10:

Might turn into this: You might need an “else” statement when your code requires more parameters without using a series for each one!

Example

var a = 0;

if (a > 0) {
  $("#display").text(a + " is greater than 0");
} else if (a < 0) {
  $("#display").text(a + " is greater than 0");
} else {
  $("#display").text("a is equal to 0");
}

Nested If condition:

The JavaScript Else Statement allows us to print different statements depending upon the expression result (TRUE, FALSE). Sometimes we have to check even further when the condition is TRUE. In this situation, it might be best for you to use a JavaScript Nested IF statement in order not to get yourself into trouble!

if ( test condition 1)
{
   if ( test condition 2)
   {
 //   do somthing 
   }

   else
   {
//   do somthing
   }

else
{
 //do somthing 
}

In the above blog post, we have a jquery if else statement. jquery if-else is a javascript statement that allows you to create conditionals for the execution of jquery code due to its ability to run different jquery codes based on the input in order to meet any jquery requirements.

Conclusion:

We hope this article has helped you to better understand how jQuery can be used for conditional statements and if-else logic. If it’s not enough, we have more tutorials on Jquery that cover a range of topics from the basics to advanced techniques. Remember, there are always new things to learn in programming!
