Mitt första javascript

Efter mycket om och men så lyckades jag ordna ett fint litet javascript som läste en renderad tabell från ett annat javascript. Så här blev det!

<br /><script type="text/javascript"><br />var upImage = "../images/up.gif";<br />var downImage = "../images/down.gif";<br />var lastChange = document.getElementsByTagName("tr");<br />var variation = document.getElementById("variation");<br />var current = document.getElementById("current");<br />var time = document.getElementById("time");<br />var image = document.getElementById("image");<br /><br />var stringTime = lastChange[3].childNodes[1]<br /> .innerText.replace("Latest update", "");<br />stringTime = stringTime.replace("AM", "");<br />stringTime = stringTime.replace("PM", "");<br />stringTime = trim(stringTime);<br /><br />var market = document.getElementById("marketValue");<br />var marketCap = document.getElementById("marketCap");<br />var strMarket = market.innerText;<br /><br />strMarket = strMarket.replace("Market Value:", "");<br />strMarket = trim(strMarket);<br /><br />marketCap.innerHTML = strMarket;<br /><br />time.innerHTML = stringTime;<br />variation.innerHTML = lastChange[2].childNodes[1].innerText;<br />current.innerHTML = lastChange[2].childNodes[3].innerText;<br /><br />if (variation.innerHTML.indexOf("-") > -1)<br /> image.setAttribute('src', downImage);<br />else if (variation.innerHTML.indexOf("+") > -1)<br /> image.setAttribute('src', upImage);<br /><br />function trim(str) {<br /> return str.replace(/^\s+|\s+$/g, "");<br /> }<br /></script><br />
