Question

在任何人爆炸之前，我是新编码的人。我尝试了几件事似乎什么都没有用，而且我害怕我已经解决了。

问题。

// Each of these sample items should have a reference to a particular
    // group.
    var sampleItems = [
        { group: sampleGroups[0], title: "Ticker 1", subtitle: "2278.59" , txt1: "+ 11.52", txt2: "+ 0.59%", description: itemDescription, content: itemContent, backgroundImage: "../../images/Assets/itemUpArrow.png" },

我制作了一个api自动收报机，我通常使用

<div id="ticker"</div>

我怎么不能用它来代替“2278.59：副标题。有什么方法可以解决这个问题而不必失去理智吗？我只想要外部的api数据在那个位置。

更新：这就是我想要做的事情：

{ group: sampleGroups[0], title: "Lorem Ipsusssm", subtitle: "<div id="ticker"> </div>", txt1: "+ 11.52", txt2: "+ 0.59%", description: itemDescription, content: itemContent, backgroundImage: "../../images/Assets/itemUpArrow.png" },

我怎么得到Javascript运行时错误：syntaxerror。

也是这个

Warning 4   Validation (HTML5): Element 'div' cannot be nested within element 'h4'. C:\Users\Noah\Desktop\Development\ah\pages\groupedItems\groupedItems.html   82  55

Answer 1

不确定您的问题是什么，但问题可能是您没有关闭div标签。

<div id="ticker"> </div>

应该修复它，但也在div中添加[space]，因此它不被视为空值

Answer 2

修改

如果无法提供帮助，请忽略以下内容，但请点击上面的更新：

subtitle: "<div id="ticker"> </div>"

这会导致语法错误。替换为：

subtitle: "<div id='ticker'> </div>"

你忘记了你的数组上的结束]（虽然因为只有一个对象你可能只是把它作为没有括号的直接对象）。

从以下两个选项中选择：

 var sampleItems = [{
     group: sampleGroups[0],
     title: "Ticker 1",
     subtitle: "2278.59",
     txt1: "+ 11.52",
     txt2: "+ 0.59%",
     description: itemDescription,
     content: itemContent,
     backgroundImage: "../../images/Assets/itemUpArrow.png"
 }]

或我的建议（假设此数组中没有其他对象）：

 var sampleItems = {
     group: sampleGroups[0],
     title: "Ticker 1",
     subtitle: "2278.59",
     txt1: "+ 11.52",
     txt2: "+ 0.59%",
     description: itemDescription,
     content: itemContent,
     backgroundImage: "../../images/Assets/itemUpArrow.png"
 }

Answer 3

如果你想迭代数组对象的属性并希望改变它的值，那么它对你有用

<!DOCTYPE html>
<html>
<head>
<script>
 // group.
 //please remove sampleGroups, itemDescription, itemContent when you use this code
 var sampleGroups = ['f', 'g'];
 var itemDescription= "ss";
 var itemContent= "aa";
    var sampleItems = [
        { group: sampleGroups[0], title: "Ticker 1", subtitle: "2278.59" , txt1: "+ 11.52", txt2: "+ 0.59%", description: itemDescription, content: itemContent, backgroundImage: "../../images/Assets/itemUpArrow.png" },
        { group: sampleGroups[0], title: "Ticker 2", subtitle: "3333", txt1: "+ 11.52", txt2: "+ 0.59%", description: itemDescription, content: itemContent, backgroundImage: "../../images/Assets/itemUpArrow.png" }
        ];

    //put the value into relaceVal in order which you 
    //want to replace with elements of sampleItems
    var replaceVal = [230, 582];
    for(var i=0; i<sampleItems.length; i++){
        for(key in sampleItems[i]){
            if(key == 'subtitle'){
                sampleItems[i].subtitle = replaceVal[i];
            }
        }
    }

     //alert new value  230, 582 respectively
    alert(sampleItems[0].subtitle);
    alert(sampleItems[1].subtitle);
</script>
</body>
</html>
