在正文加载时调用 javascript 函数或直接从脚本调用 javascript 函数之间的区别
我正在使用javascript，其中我在运行时创建多个div（比如5），使用javascript函数，所有div都包含一些文本，这些文本再次在运行时设置，现在我想在运行时禁用所有div并让页码在底部，这样每当用户单击页码时，只有该 div 应该可见，否则其他应该被禁用，我创建了一个函数，它接受参数作为页码，我启用页码被单击的 div并使用for循环，我禁用所有其他div，现在我的问题是我创建了两个函数，第一个（用于添加div并禁用除第一个之外的所有div）并向其写入内容，另一个用于启用其div点击页码，我在body onload上调用了Adding div函数；现在，当我第一次运行时，页面一切顺利，但下次当我单击任何页码时，它就会被启用，并且 AddDiv 函数再次运行并重新启用所有 div。
请回复为什么这是发生的情况以及我应该如何解决我的问题...
下面是我的脚本，div 的内容使用 Json 来。
<body onload="JsonScript();">
<script language="javascript" type="text/javascript">
function JsonScript()
{
var existingDiv = document.getElementById("form1");
var newAnchorDiv = document.createElement("div");
newAnchorDiv.id = "anchorDiv";
var list = { "Article": articleList };
for(var i=0; i < list.Article.length; i++)
{
var newDiv = document.createElement("div");
newDiv.id = "div"+(i+1);
newDiv.innerHTML = list.Article[i].toString();
newAnchorDiv.innerHTML += "<a href='' onclick='displayMessage("+(i+1)+")'>"+(i+1)+"</a> ";
existingDiv.appendChild(newDiv);
existingDiv.appendChild(newAnchorDiv);
}
for(var j = 2; j < list.Article.length + 1; j ++)
{
var getDivs = document.getElementById("div"+j);
getDivs.style.display = "none";
}
}
function displayMessage(currentId) {
var list = {"Article" : articleList}
document.getElementById("div"+currentId).style.display = 'block';
for(var i = 1; i < list.Article.length + 1; i++)
{
if (i != currentId)
{
document.getElementById("div"+i).style.display = 'none';
}
}
}
</script>
感谢和问候
i am using a javascript where in i am creating multiple div (say 5) at runtime, using javascript function, all the divs contain some text, which is again set at runtime, now i want to disable all the divs at runtime and have the page numbers in the bottom, so that whenever user clicks on the page number only that div should get visible else other should get disable, i have created a function, which accepts parameter, as page number, i enable the div whose page number is clicked and using a for loop, i disable all the other divs, now here my problem is i have created two functions, 1st (for adding divs and disabling all the divs except 1st) and writing content to it, and other for enabling the div whose page number is clicked, and i have called the Adding div function on body onload; now first time when i run, page everthing goes well, but next time when i click on any of the page number, it just gets enabled and again that AddDiv function, runs and re-enables all the divs..
Please reply why this is happening and how should i resolve my issue...
Below is my script, content for the div are coming using Json.
<body onload="JsonScript();">
<script language="javascript" type="text/javascript">
function JsonScript()
{
var existingDiv = document.getElementById("form1");
var newAnchorDiv = document.createElement("div");
newAnchorDiv.id = "anchorDiv";
var list = { "Article": articleList };
for(var i=0; i < list.Article.length; i++)
{
var newDiv = document.createElement("div");
newDiv.id = "div"+(i+1);
newDiv.innerHTML = list.Article[i].toString();
newAnchorDiv.innerHTML += "<a href='' onclick='displayMessage("+(i+1)+")'>"+(i+1)+"</a> ";
existingDiv.appendChild(newDiv);
existingDiv.appendChild(newAnchorDiv);
}
for(var j = 2; j < list.Article.length + 1; j ++)
{
var getDivs = document.getElementById("div"+j);
getDivs.style.display = "none";
}
}
function displayMessage(currentId) {
var list = {"Article" : articleList}
document.getElementById("div"+currentId).style.display = 'block';
for(var i = 1; i < list.Article.length + 1; i++)
{
if (i != currentId)
{
document.getElementById("div"+i).style.display = 'none';
}
}
}
</script>

尝试将
return false;添加到页面链接以防止重新加载页面。Try adding
return false;to the page link to prevent the page from being reloaded.您的页面链接正在重新加载页面。您只需更改一行，您的脚本就可以正常工作。
Your page links are reloading the page. You just have to change one line and your script works ok.
