如何使用jQuery从.each循环创建数组

Question

如何从'.each循环'内部创建一个数组并在循环之外使用它？

我的.each loop:

       // Loop through all but button with class .apply
        $('.profile-nav ul li a').not('.apply').each( function() {

            // if currently loop through element has .cur class
            if( $(this).hasClass('cur') ) {


                //Get the first class of the match element                  
                var ClassesToApply = $(this).prop('class').split(' ')[0];

            }   
            //How can I create an array from all ClassesToApply?


            //var arr = jQuery.makeArray(ClassesToApply);
            // This will create an array, but with one element only

        });

如何从所有人创建一个数组var = ClassesToApply？

而且我怎么能用这个数组做点什么呢？例如

$( allClasses from an array as a selectors).doStuff();

Answer 1

如果你在变量之外声明一个变量each,它将在以下内容中可访问each:

var yourArray = [];
$('.profile-nav ul li a').not('.apply').each(function() {
    if($(this).hasClass('cur')) {
        yourArray.push($(this).prop('class').split(' ')[0]);
    }
});
//Here, yourArray will contain the strings you require.

虽然正如其他人所示,但有很多方法可以显着缩短代码.

fxnReqValidation = function () {
        var InputTagArray = new Array;
        InputTagArray = document.getElementsByTagName("input");
        for (var iCnt = 1; iCnt <= InputTagArray.length; iCnt++) {
            if ((g_Json[InputTagArray[iCnt].name].required == true) && (InputTagArray[iCnt].value == "")) {
                $("#errormsg").text("please enter all required fields");
            }
            return false;
        }
    }

你可以这样做:

var arr = $( 'a.cur:not(.apply)', '.profile-nav' ).map( function () {
    return $( this ).prop( 'class' ).split( ' ' )[0];
}).get();
