inArray inArray方法用于检查一个元素是否存在于数组中。它接受两个参数:需要查找的元素和可选的起始索引。如果找到该元素,则返回其索引;如果未找到,则返回-1。 示例代码: 代码语言:javascript 复制 constarr=[1,2,3,4,5];constresult=$.inArray(3,arr);console.log(result);// 2 ...
arguments[1] : void 0; for (var i = 0; i < len; i++) { if (i in t) { var val = t[i]; // NOTE: Technically this should Object.defineProperty at // the next index, as push can be affected by // properties on Object.prototype and Array.prototype. // But that method's...
Thefind()method does not change the original array. Array Find Methods: MethodFinds indexOf()The index of the first element with a specified value lastIndexOf()The index of the last element with a specified value find()The value of the first element that passes a test ...

The FindIndex<T>(T[], Predicate<T>) method overload traverses the array from the beginning, passing each element in turn to the EndsWithSaurus method. The search stops when the EndsWithSaurus method returns true for the element at position 1....
Searches for an element that matches the conditions defined by a specified predicate, and returns the zero-based index of the first occurrence within an Array or a portion of it.
The steps for find values of nonzero value using find values in array: Step 1:We need to collect all inputs in one set or in an array. Step 2:Then, we use a find value in array with proper syntax to find the nonzero element values. ...
The find() method returns the value of the first element in an array that pass a test (provided as a function).The find() method executes the function once for each element present in the array:If it finds an array element where the function returns a true value, find() returns the ...
The FindIndex<T>(T[], Predicate<T>) method overload traverses the array from the beginning, passing each element in turn to the EndsWithSaurus method. The search stops when the EndsWithSaurus method returns true for the element at position 1. Note In C#, F#, and Visual Basic, it is...
of the array. It finds the element at position 5. Finally, theFindIndex<T>(T[], Int32, Int32, Predicate<T>)method overload is used to search the range of three elements beginning at position 2. It returns -1 because there are no dinosaur names in that range that end with "saurus...
