我创建了一个变量并使用push属性添加了新值,但是当for循环逐个调用它时,它只打印最后一个值(名称),即" Pranav"。你能帮助我知道如何解决它并逐个打印所有值。
function tryme() {
var names = new Array();
names.push("Bhavesh", "Ajay", "Rahul", "Vinod", "Bobby", "Pranav");
var tryit = document.getElementById("tryit");
for (i = 0; i < names.length; i++) {
tryit.innerHTML = "The values are " + names[i] + " . <br>"
};
};

每次循环都会替换innerHTML
属性的值。你可能意味着追加而不是替换。所以......
改变这个:
tryit.innerHTML = "The values are " + names[i] + " . <br>"
到此:
tryit.innerHTML += "The values are " + names[i] + " . <br>"

问题在于,在这一行中,您将innerHTML设置为单个名称,因此每次都会被覆盖:
tryit.innerHTML = "The values are " + names[i] + " . <br>"
尝试将其更改为附加或类似内容:
tryit.innerHTML += "The values are " + names[i] + " . <br>"

在字符串上使用时,+
运算符称为concatenation
运算符。
因此,+=
将意味着追加以前的价值。
function tryme() {
var names = new Array();
names.push("Bhavesh","Ajay","Rahul","Vinod","Bobby","Pranav");
var tryit = document.getElementById("tryit");
tryit.innerHTML += "The values are<br>";
for (i=0;i<names.length;i++) {
tryit.innerHTML += names[i] + "<br>"
};
};
tryme();
