Adding the AngurJS filter to Capitalize the first word, all words or all UPPERCASE

First, create the file 'capitalize.js' with the following contents.

/* capitalize.js file contents */

myapp.filter('capitalize', function() {
    return function(input, all) {
        var reg = (all) ? /([^\W_]+[^\s-]*) */g : /([^\W_]+[^\s-]*)/;
        return (!!input) ? input.replace(reg, function(txt){return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();}) : '';
    };
});

Then use the below example to adopt the code in your contexts;

To Capitalize the first word only
{{name | capitalize}} 
OUTPUT: "Hello world nepal"

To Capitalize the all words
{{name | capitalize:true}} 
OUTPUT: "Hello World Nepal"

The below example is for Data Table (angular-laravel library) rending html case:

/* In Data table rending html case */

var data = 'hello world nepal';
.renderWith(function (data, type, full) {
 return $filter('capitalize')(data)
})

// OUTPUT: "Hello world nepal"

.renderWith(function (data, type, full) {
 return $filter('capitalize')(data, true)
})
// OUTPUT: "Hello World Nepal"

/* and, For UPPERCASE */
.renderWith(function (data, type, full) {
 return data.toUpperCase();
})

// OUTPUT: "HELLO WORLD NEPAL"
