I'm attempting
to write a Ubiquity command that allows you
to replace a selected link or URL pointing
to an image with that image itself. However, the CmdUtils.setSelection() function (documented here) seems
to do nothing if any html tags are present in the selection, making it useless for replacing any links. When selecting
plain text, it functions exactly as intended, replacing the
text with an <img src="
text"/> tag. Is there something I'm missing, or will this function simply not allow me
to replace html? If the latter is the case, is there a function or method that will allow me
to do this? Any other advice is welcome as well!
CmdUtils.CreateCommand({
name: "fetch-image",
author: {name: "Josh Timmer"},
license: "GPL",
description: "Replaces links or URLs pointing
to images with the image itself",
help: "Highlight
text or a hyperlink and execute this command",
takes: {"image URL": /.*/},
_getImgUrl: function(itemIq) {
if (itemIq.html.indexOf("<a ",0) < 0)
return itemIq.text;
var refPos = itemIq.html.indexOf("href=\"",0);
if (refPos < 0)
return "Error, no URL found!";
var startPos = itemIq.html.indexOf("\"", refPos);
var endPos = itemIq.html.indexOf("\"", startPos + 1);
startPos += 1;
var url = itemIq.html.substring(startPos, endPos);
return url;
},
preview: function(pblock, input) {
pblock.innerHTML = "Image URL: " + this._getImgUrl(input) + "<br/><br/><img src='" + this._getImgUrl(input) + "'/>";
},
execute: function img_insert(input) {
CmdUtils.setSelection("<img src='" + this._getImgUrl(input) + "'/>");
displayMessage("Executed: " + this._getImgUrl(input));
}
});
