Hi all,
The following script is a task I set myself to learn javascript, essentially there are several arrays containg keywords which, depending on the array, should highlight those words in different colours.
The code works but I get an unresponsive script error and it's very slow. I think because of the document.body innerhtml part as I tried keyword swaps and it was fine.
var textnodes = document.evaluate( "//body//text()", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
for (var i = 0; i < textnodes.snapshotLength; i++)
{
node = textnodes.snapshotItem(i);
node.data = highlight(node.data);
}
function highlight()
{
for (var j = 0; j < testArrayOne.length; j++)
{
document.body.innerHTML = document.body.innerHTML.replace(new RegExp(testArrayOne[j]),'<span style="color:#ff0000">' + testArrayOne[j] + '</span>');
}
for (var j = 0; j < testArrayTwo.length; j++)
{
document.body.innerHTML = document.body.innerHTML.replace(new RegExp(testArrayTwo[j]),'<span style="color:#FF00FF">' + testArrayTwo[j] + '</span>');
}
}
Thanks for your help.
P.S. this is a userscript for greasemonkey
