javascript - How to assign a class and toggle a expandable menu item - 


$('.mybutton').click(function() {     var vstr = "2.1";     var vulsize = $("#uspstyle li:not(li li)").size();     var vulsubsize;     if (vstr.indexof('.') !== -1) {         var vsplit = vstr.split(".");         var vfirst = vsplit[0];         var vsecond = vsplit[1];         console.log(vfirst); //first number         console.log(vsecond); //second number         console.log(vulsize); //size of parent ul         if (vfirst <= vulsize) { //if first number less or equal parent ul size             //{need help}remove 'current' class existing parent li             $("#uspstyle li:eq(" + vfirst + ")").addclass("current"); //{need help}add 'current' class parent li             vulsubsize = ""; //{need help}get size of sub ul inside above li             if (vsecond <= vulsubsize) { //if number less or equal size of sub ul                 $("#uspstyle li:eq(" + vfirst + ")").find("ul").slidetoggle(); //{need help}expand sub ul inside li                 $("#uspstyle li:eq(" + vfirst + ")").find("ul li:eq(" + vsecond + ")").addclass("current"); //{need help}add 'current class sub ul li                 $('.dispartbody').addclass('hidecontent'); //{need help}hide content                 var element = $("#uspstyle li:eq(" + vfirst + ")").find("ul li:eq(" + vsecond + ")").attr("data-toggle"); //{need help}get class of li corresponds body class                 $(element).removeclass('hidecontent'); //{need help}show content corresponds element             }         }     }     else {         //{need help}remove 'current' class existing parent li         $("#uspstyle li:eq(" + vfirst + ")").addclass("current"); //{need help}add 'current' class parent li         $('.dispartbody').addclass('hidecontent'); //{need help}hide content         var element = $("#uspstyle li:eq(" + vfirst + ")").attr("data-toggle"); //{need help}get class of li corresponds body class         $(element).removeclass('hidecontent'); //{need help}show content corresponds element     } });

fiddle: http://jsfiddle.net/5qweu58f/6/

for example, if vstr 2.1 "care" li should lose current class , "bc" li should current class. "our link" li should current class , <div class="tf1slink2 dispartbody hidecontent"><tf1stext02>this second link sublink 1</tf1stext02></div> should displayed because corresponds first li of sub ul second li of parent ul.

please me complete script above accomplish that. removeclass , addclass not working @ me.

i trying replicate click event through page load event. 2.1 in url, example: www.mysite1.com/mypage.aspx?id=9090&menuid=2.1

only minor edit:

if (vfirst <= vulsize) {     // remove .current every top level sure     $("#uspstyle li a").removeclass("current");      // next line accomplishes 2 goals:     // adds .current tag inside correct li (you adding li)     // gets size vulsubsize (you setting "" reason)     vulsubsize = $("#uspstyle > li:eq(" + (vfirst-1) + ") a").addclass("current").size();

you can see above i've specified li has direct descendant of $("#uspstyle") when add .current, because there other lower lever children should not applied to. use (vfirst-1) - because :eq() works on index basis, 1 in string equates 0th element.

corrected fiddle

for second level (after edits), want use 

$("#uspstyle > li:eq(" + vfirst + ") > ul > li:eq(" + vsecond + ") a").addclass("current");

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
