正如标题中所说,我无法展示生命中的另一个div 我的。请查看并告诉我为什么我无法显示“id = output1”?
以下是html:
<input type="button" value="Insert Queue Length" onClick="InitializeQueue();" />
<br/>
<div id="output">
<br/>
<div id="output1">
<br/>
以下是带有排队功能和方法的javascript
function Queue(){
var count = 0;
var head = null;
var tail = null;
this.GetCount = function(){
return count;
}
this.Enqueue = function (data) {
//fill queue
var node = {
data: data,
next: head
};
if (head === null) {
tail = node;
}
head = node;
count++;
}
this.Dequeue = function () {
//if queue is empty, returns null
if (count === 0) {
return;
}
else {
var current = head;
var previous = null;
while (current.next) {
previous = current;
current = current.next;
}
if (count > 1) {
previous.next = null;
tail = previous;
}
else {
head = null;
tail = null;
}
count--;
}
}
this.DisplayAll = function () {
if (head === null) {
return null;
}
else {
var arr = new Array();
var current = head;
for (var i = 0; i < count; i++) {
arr[i] = current.data;
current = current.next;
}
arr = arr.reverse();
return arr;
}
}
}
这将创建一个链接列表并向其添加节点
var L1 = new Queue();
function InitializeQueue() {
var iteration = 0;
var y = parseInt(document.getElementById("QueueLength").value);
for(i = 2; i <= y; i++){
L1.Enqueue(i);
document.getElementById("output").innerHTML = "L1: "+ L1.DisplayAll();
}
L1.Dequeue();
//For some reason this wont display, but the dequeue seems to work properly
document.getElementById("output1").innerHTML = "L1: "+ L1.DisplayAll();
}
</script>
答案 0 :(得分:0)
你确定你不需要关闭div吗?如果这不是问题,请创建一个小例子。
<input type="button" value="Insert Queue Length" onClick="InitializeQueue();" />
<br/>
<div id="output"></div>
<br/>
<div id="output1"></div>
<br/>
