if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
 xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

setTimeout(function(){
xmlhttp.open("GET","some.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
var x=xmlDoc.getElementsByTagName("offer");
var page = parseInt(x.length) / 10;
document.write("<div class='pagination_btn_cont'>");
for (i=1;i<=page;i++)
{ 
 document.write("<div class='pagination_btn'>"+i+"</div>");

},10000);

</script>

when i open the webpage its display all the content of the page but after 10 seconds the page will become blank and display only the numbers which i am getting from the loop.

回答1:

You can use innerHTML in javascript. It use to insert data to particular div without affecting page contents.

Example:

var results = "";
for(var i=1;i<=10;i++)
{
     results += "<div class='pagination_btn'>"+i+"</div>";
}
document.getElementById("your result show div id").innerHTML = results;

you can specify $('.pagination_btn').bind("click")... inside your document.ready

回答2:

Use innerHtml to change text of a specific element.

HTML

<div id="container"></div>

javascript

document.getElementById('container').innerHTML += '<div>content</div>';

or you can use jQuery library, life will be much easier:

$("#container").append("<div>content</div>");

回答3:

try this

document.getElementsByTagName('body').innerHTML += '<div id="parent" class="pagination_btn_cont">';

for (i=1;i<=page;i++)
{ 
 document.getElementById('parent').innerHTML = "<div class='pagination_btn'>"+i+"</div>";
}
