循环jQuery对象并返回值

Posted 2021-02-26

Returning a boolean inside of jQuery's $.each() function will only break the loop. To get a return value, you can convert the jQuery object to array and use a regular for loop in javascript.

var checkBoxes = $(':checkbox');
 
var allAreSelected = (function() {
 
	for (i in checkBoxes.get()) {
		if (!checkBoxes[i].checked) { 
			return false; 
		}
	}
 
	return true;
 
})();
