Question

我正试图在TVOS productTemplate内动态更新英雄形象源。

我能够为描述做到这一点，例如：

function changeDescription(incomingString) {
    if (incomingString) {
        var theDescription = myDoc.getElementsByTagName("description").item(0);
        theDescription.innerHTML = incomingString;
    }
}

..但它不适用于英雄形象的src值：

function changeHeroImage(incomingString) {
    console.log("local path: " + incomingString)
    if (incomingString) {
        var theHero = myDoc.getElementsByTagName("heroImg").item(0);
        var theHeroSrc = theHero.getAttribute("src");
        theHeroSrc.value = incomingString;
        // theHeroSrc.innerHTML = incomingString;
    }
}

我已经证实路径是正确的;我还应该看看还有什么？

Answer 1

更新图片应使用src属性，而不是value：

function changeHeroImage(incomingString) {
    console.log("local path: " + incomingString)
    if (incomingString) {
        var theHero = myDoc.getElementsByTagName("heroImg").item(0);
        theHero.src = incomingString;
    }
}

Answer 2

尝试setAttribute

theHero.setAttribute('src', incomingString)

更新TVOS模板中的“Hero Image”
