var cb = $("input:checkbox[name='cbgw-xz'][value='" + gwid + "']");
var chk = cb.is(':checked');
console.log(chk);
if (chk == true) {
cb.prop('checked', false);

}
});
if (str.length > 0) {
str = str.substring(0, str.length - 1);
}
return str;
}

var bkgw = getcheckboxvalues('cbgw-xz');

//设置checkbox组的选中状态，依据是传入值 (示例：'1,2,3')
function setcheckboxcheck(cbname, array) {
var tj = array.split(',');
$("input[name^='"+cbname+"']").each(function () {
if (tj.indexOf(this.value) >= 0) {
this.checked = true;
}
});
}

var tjs = '4,34';
