Hii,
This blog is in continuation with my previous blog on directives in angularJs, in this blog, I will discuss expressions in angularJs.
- In angularJs "Expression" are used to bind data to HTML.
- Expression were written inside two curly braces,and contain operators, variables, and literals.
Syntax:{{ expression }}
- As we know angularJs is a framework of javascript,many similarities are there like angularJs expressions are also very similar to javascript expressions.
- Basically, angularJs is an efficient and easy way or method to use JavaScript functionalities, such as operators, variables, conditions etc to HTML.
Example:
We can use angularJs expressions when we want to assign any string value dynamically using an Angular directive .
In this example, a string value is added.
<div ng-app ng-init="name='Pinky'">
My name is {{ name }}
</div>
Output
My name is Pinky
Example:
We can use angularJs expressions when we want to assign any number dynamically using an Angular directive.
In this example a numeric value is added,Numeric values can also be a decimal values.
<div ng-app>
I have total Rs{{3000}} in my pocket.
</div>
Output
I have total Rs3000 in my pocket.
