reactjs - React.js how to return commented video tag for ie9 support -


let's in react want support ie9 wrapping code, example picturefill does:

<picture>   <!--[if ie 9]><video style="display: none;"><![endif]-->   <source srcset="examples/images/extralarge.jpg" media="(min-width: 1000px)">   <source srcset="examples/images/large.jpg" media="(min-width: 800px)">   <!--[if ie 9]></video><![endif]-->   <img srcset="examples/images/medium.jpg" alt="…"> </picture>

in react, be:

return (                 <picture>                 <!--[if ie 9]><video style="display: none;"><![endif]-->                 <source type="image/webp" classname="full-photo2 slide-init" srcset={"./build/assets/images/photos/responsive/webp/" + image.id + "-400.webp 400w, ./build/assets/images/photos/responsive/webp/" + image.id + "-800.webp 800w, ./build/assets/images/photos/responsive/webp/" + image.id + "-1000.webp 1000w,"} />                 <img classname="full-photo2 slide-init" srcset={"./build/assets/images/photos/responsive/jpg/" + image.id + "-400.jpg 400w, ./build/assets/images/photos/responsive/jpg/" + image.id + "-800.jpg 800w, ./build/assets/images/photos/responsive/jpg/" + image.id + "-1000.jpg 1000w,"} />                 <!--[if ie 9]></video><![endif]-->               </picture>  )

of course, react gets angry this.

so how can return ie9 hacks in react returns?

with caveats using dangerouslysetinnerhtml per above link, have made work (using es6):-

const createmarkup = () => {   return  {__html:     `<!--[if ie 9]><video style="display: none;"><![endif]-->     <source srcset="examples/images/extralarge.jpg" media="(min-width: 1000px)">     <source srcset="examples/images/large.jpg" media="(min-width: 800px)">     <!--[if ie 9]></video><![endif]-->     <img src="examples/images/medium.jpg" alt="…">`   }; };  return (   <picture dangerouslysetinnerhtml={createmarkup()}>   </picture> )

you can of course pass arguments createmarkup function , interpolate within template string placeholders using ${ } syntax (getting literal es6 template strings):-

const createmarkup = (path) => {   return  {__html:     `<!--[if ie 9]><video style="display: none;"><![endif]-->     <source srcset="${path}extralarge.jpg" media="(min-width: 1000px)">     <source srcset="${path}large.jpg" media="(min-width: 800px)">     <!--[if ie 9]></video><![endif]-->     <img src="${path}medium.jpg" alt="…">`   }; };  return (   <picture dangerouslysetinnerhtml={createmarkup('examples/images/')}>   </picture> )

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

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...
