how can I insert some HTML code between <div id="mydiv">...</div>
using javascript?
Ex: <div id="mydiv"><span class="prego">Something</span></div>
its about 10 lines of html of most. thank you
如果您要替换 div 的内容并将 HTML 作为字符串,则可以使用以下内容:
document.getElementById('mydiv').innerHTML = '<span class="prego">Something</span>';
A simple way to do this with vanilla JavaScript would be to use appendChild
.
var mydiv = document.getElementById("mydiv");
var mycontent = document.createElement("p");
mycontent.appendChild(document.createTextNode("This is a paragraph"));
mydiv.appendChild(mycontent);
Or you can use innerHTML
as others have mentioned.
Or if you would like to use jQuery, the above example could be written as:
$("#mydiv").append("<p>This is a paragraph</p>");
// Build it using this variable
var content = "<span class='prego'>....content....</span>";
// Insert using this:
document.getElementById('mydiv').innerHTML = content;
That's really kind of an ambiguous request. There are many ways this can be accomplished.
document.getElementById('mydiv').innerHTML = '<span class="prego">Something</span>';
That is the simplest . OR;
var spn = document.createElement('span');
spn.innerHTML = 'Something';
spn.className = 'prego';
document.getElementById('mydiv').appendChild(spn);
Preferred to both of these methods would be to use a Javascript library that creates shortcut methods for the simple things like this, such as mootools. ( http://mootools.net )
With mootools this task would look like:
new Element('span', {'html': 'Something','class':'prego'}).inject($('mydiv'));
document.getElementById("mydiv").innerHTML = "<span class='prego'>Something</span>";
Should do it. If you are willing to use jQuery it could be easier.
document.getElementById('mydiv').innerHTML = 'whatever';
Javascript
document.getElementById('mydiv').innerHTML = '<span class="prego">Something</span>';
jQuery
$("#mydiv").append('<span class="prego">Something</span>');
