javascript - OnMouseOver / OnMouseOut -


i'm using onmouseover , onmouseout function change colour of social media icons in footer of wordpress website: http://www.retelevise.com.

it works fine, i'm using snippet of javascript link email address (i read somewhere way hide address spammers?) – javascript doesn’t seem mouse function. 

    <script type="text/javascript">     <!--     var addr1 = "mailto:"     var addr2 = "info"     var addr3 = "@"     var addr4 = "retelevise"     var addr5 = ".com"     document.write('<a href="' + addr1 + addr2 + addr3 + addr4 + addr5 + '">')     document.write('<img src="http://www.retelevise.com/wp-content/themes/myownzee/branding/socialmedia-email-1.png" onmouseover="this.src='http://www.retelevise.com/wp-content/themes/myownzee/branding/socialmedia-email-2.png'" onmouseout="this.src='http://www.retelevise.com/wp-content/themes/myownzee/branding/socialmedia-email-1.png'" class="social-icons-main" title="email" alt="email"></a>');      //-->     </script>

if remove mouse function, grey email icon appears without switching colour version on hover, when try adding mouse code, email icon disappears altogether. did @ similar answers posted here, sorry didn't understand them. have ideas please?

thanks, sn.

there no escaping of single quotes used within single quoted value.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
