javascript - Confusion regarding selectors in carousel/slider -

-

so i'm pretty new javascript/jquery. i've made website, changes color of frame depending on select carousel/slider.

everything operational, issue is, can't quite wrap head around how apply selector elements of carousel.

basically carousel looks this

carousel

what want do, is, i've set third border/frame hidden. now, whenever click left arrow element closest left switch hidden, while, image right of take it's position , hidden image appear.

the opposite goes right, i've made this:

carousel working

so working expected, issue is, work once (mainly because don't know selector use).

to put things context, html (specifically carousel) looks this

    <div id="selector">     <img id="goleft" src="images/left.png" />     <div>         <img id="blue" src="images/shot-blue.png" />         <img id="yellow" src="images/shot-yellow.png" />         <img id="red" src="images/shot-red.png" />     </div>     <img id="goright" src="images/right.png" /> </div>

nothing difficult

my jquery basic well

<script type="text/javascript">     $(document).ready(function() {       //set last (red) image hidden       $("#selector div img:last").hide();       // if click left, hide first 1 , show last 1       $("#goleft").click(function(){         $("#selector div img:first").hide('slow')         $("#selector div img:last").show('slow')       });       // similar right       $("#goright").click(function(){         $("#selector div img:last").hide('slow')         $("#selector div img:first").show('slow')       });     }); </script>

only issue is, :first , :last selector literally select first , last image instead of first visible , last hidden element

so carousel stops working after first rotation (on both sides)

any idea how apply selector rotation endless?

the :first , :last selector literally select first , last image instead of first visible , last hidden element

you can use hidden , visible selector , use last , first methods of jquery:

$("#selector div img:hidden").first().show();     $("#selector div img:visible").last().hide();

update: note can not run these statements 1 after otherwise have jquery execute statements on not yet hidden. can prevent use callback function on show , hide this:

$("#selector div img:visible").last().hide('slow', function()     {       $("#selector div img:hidden").first().show('slow');     } );

here jsfiddle full implementation:

i used span css instead of images need change span img own case.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
