$.grep() filter function array filtering in jQuery
<pre code_snippet_id="1998964" snippet_file_name="blog_20161122_1_1873395" name="code" class="html">var = $.grep([1,32,5,63,8,4,-8,-5,2,56,9,62,-6],function (n , i){
if(n>50){
return n;
}
});
console.log(test);
$.grep(array,callback,[invert]) has two parameters. The first parameter is the array to be filtered, and the second parameter is the array to be filtered. The first parameter is the filtering condition, and the third parameter (optional) is to retain the element (true) or delete the element (false).
var = $.grep([1,32,5,63,8,4,-8,-5,2,56,9,62,-6],function (n , i){
if(n>50){
return n;
}
}，true);
console.log(test);
---->[63,56,62]
var = $.grep([1,32,5,63,8,4,-8,-5,2,56,9,62,-6],function (n , i){
if(n>50){
return n;
}
}，false);
console.log(test);
---->[1,32, 5,8,4,-8,-5,2,9,-6]
The above is the $.grep() filter function array filtering in jQuery introduced by the editor. I hope it will be helpful to everyone
