Jquery 加js 字符串应用查找 checkbox 被选中数

1. 选择所有

?

function allChoose() {    var checkChoose = $("#allCheckbox");    var all = checkChoose.attr("checked");   if (all) {var ch = $.find("input[type=checkbox]");$.each(ch,function(){$(this).attr("checked",true);});   }   else {   var ch = $.find("input[type=checkbox]");$.each(ch,function(){$(this).attr("checked",false);});   }    }

2. 得出选中后的值

?

 function getChooseValue() {        var chooseCheckbox = $.find("input[type=checkbox]");    var str = new String();    var length = chooseCheckbox.length;    var m = 0;    $.each(chooseCheckbox,function(index) {    if ($(this).attr("name") == "chooseReport"    && $(this).attr("checked")) {    if (m != 0) {    str = str + ",";    }    m++;    str = str.concat($(this).val());    }    });    document.write(str);    document.close();    alert(str);        }

?
