javascript - Search and replace a text sequence in html -


i trying search , replace text sequence in website. webpage has text "#45421" (# followed 5 digits). need replace <a href="http://example.com/45421">#45421</a>. tried below code this,

var mystring = $('.content').html(); var re = /\b\#d{5}\b/g; mystring.replace(re, "<a href='http://example.com/'"+re+">"+re+"</a>");

but unable desired results. see text sequence replaced links script executed. script injected page chrome extension. missing here?

you need use regex capturing groups - put parentheses around part of regex want capture, , refer in replacement string $1 (and, if you're capturing multiple, next $2 , on):

mystring.replace(/#(\d{5})\b/g, '<a href="http://example.com/$1">#$1</a>');

your regex has misplaced escape backslash - d should escaped, not #

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
