How To Search Array Keys In Javascript Jquery Using Indexof Stack

How To Search Array Keys In Javascript Jquery Using Indexof Stack If members is an object, which it looks like with the key value pairs, you can use object.keys(objvariable) to get the keys of an object to loop over and do your comparison regex logic on. The indexof() method in jquery is used to determine the position of a specified value within an array or string. if the value is found, it returns the index of the first occurrence; otherwise, it returns 1.

How To Search Through Arrays In Javascript Javascript array indexof () the indexof() method searches an array for an element value and returns its position. note: the first item has position 0, the second item has position 1, and so on. Here are the different methods to search for an item in an array in javascript 1. using indexof () the indexof () method searches for a specified value in an array and returns its first index. if the value is not found, it returns 1.

Javascript Array Indexof Method Delft Stack The jquery array indexof () function searches for the specified element in the given array, if the element found it, then it returns the first occurrence of the element from left, if the element is not found in the array, then it return 1. When one thinks of searching an array using javascript, you are tempted to use the indexof method, which is as simple as using arr.indexof (item). however remember that the indexof or lastindexof methods have been formalized in ecmascript 5.

To achieve what you want, i would loop through the array using $.each function as well as the javascript indexof function to search the string. the property of the object i would use the indexof function would be the "name" property. The return value of the indexof() function is the numeric index of that value in the target value, or 1 if it's not found. so for each value that you're looking for, you'd want to check if it's index is > 1 (which means it's found in the string). take that whole condition and || it with another condition, and that's a logical operation.
