Idea: DOI Rescue extension

DOI Rescue

Browser extension that kicks in on dx.doi.org/* and doi.org/* when a DOI hasn't been registered yet, redirects to the website and uses its search function

• I wrote an example for Nature 10 months ago, would not be hard to programmatically pull in all others for which this could happen - https://gist.github.com/lmmx/4dafda42f50514f2de9a

• extensible table of URLs and search pages, using the DOI of the publication.

[
  "Nature": { DOI_prefix: "10.1038/nature",
              URL: "http://www.nature.com/search?q=" },
  "Nature Chemistry": { DOI_prefix: "10.1038/nchem",
                        URL: "" },
  "Nature Genetics":  { DOI_prefix: "10.1038/ng",
                        URL: "" }
]              

etc.

Below this is the basic code to handle it, currently a bookmarklet but better as a minimal browser extension [i.e. one with no user activity required, like gmtfPDF]

• could be an extension to gmtfPDF...!

Bookmarklet:

javascript:(function(){if (window.location.href.indexOf('nature.com/doifinder/') > -1 && document.querySelector('span.largeParagraph > p').innerText.indexOf('DOI Handle') > -1) { doi = window.location.href.split('doifinder/')[1]; var naturexhr = new XMLHttpRequest(); naturexhr.open("GET","http://www.nature.com/search/executeSearch?sp-q="+doi.replace('/','%2F')+"&sp-p=all&pag-start=1&sp-c=25&sp-m=0&sp-s=&siteCode=default,true"); naturexhr.send(); naturexhr.onreadystatechange = function(){ if (naturexhr.readyState === 4 && naturexhr.status==200){ redirURL = naturexhr.response.match(/<h2 class="atl"><a href="(.*?)"/)[1]; window.location.href = redirURL; } } } else { alert('You need to be on the error page to do page redirect from the "invalid DOI" page'); }
})();

Full script:

if (window.location.href.indexOf('http://www.nature.com/doifinder/') > -1 && document.querySelector('span.largeParagraph > p').innerText.indexOf('DOI Handle') > -1) {
	doi = window.location.href.split('doifinder/')[1];
	var naturexhr = new XMLHttpRequest();
	naturexhr.open("GET","http://www.nature.com/search/executeSearch?sp-q="+doi.replace('/','%2F')+"&sp-p=all&pag-start=1&sp-c=25&sp-m=0&sp-s=&siteCode=default,true");
	naturexhr.send();
	naturexhr.onreadystatechange = function(){
		if (naturexhr.readyState === 4 && naturexhr.status==200){
			redirURL = naturexhr.response.match(/<h2 class="atl"><a href="(.*?)"/)[1];
			window.location.href = redirURL;
		}
	}
}
else {
	alert('You need to be on the error page to do page redirect from the "invalid DOI" page');
}
