How to check if the JSON Object array contains the value defined in an arrary or not?
Try the following:
var categories = [
{catValue:1, catName: 'Arts, crafts, and collectibles'},
{catValue:2, catName: 'Baby'},
{catValue:3, catName: 'Beauty and fragrances'},
{catValue:4, catName: 'Books and magazines'},
{catValue:5, catName: 'Business to business'},
{catValue:6, catName: 'Clothing, accessories, and shoes'},
{catValue:7, catName: 'Antiques'},
{catValue:8, catName: 'Art and craft supplies'},
{catValue:9, catName: 'Art dealers and galleries'},
{catValue:10, catName: 'Camera and photographic supplies'},
{catValue:11, catName: 'Digital art'},
{catValue:12, catName: 'Memorabilia'}
];
var categoriesJson = JSON.stringify(categories);
var mainCat = ['Arts, crafts, and collectibles', 'Baby' , 'Antiques']
$.each(JSON.parse(categoriesJson) , function (key, value) {
if(mainCat.indexOf(value.catName) > -1){
console.log('Exists: ' +value.catName)
}
else{
console.log('Does not exists: ' +value.catName)
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>I would filter the initial data array to get the array of matching categories:
var matchedCategories = categories.filter(i => mainCat.indexOf(i.catName) >= 0);
Then you could do what you need by iterating this sub-array.
