<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, the second parameter is the filtering condition, and the third parameter (optional) ) means retaining elements (true) or deleting elements (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]
