javascript - how to repeat the left menubar in each html page -
var navigation = new array(); // navigation. // ==================== navigation ==================== // navigation[0] = '<div id="menu">'; navigation[1] = '<ul>'; navigation[2] = '<li><a href="../about_us.htm">aboutus</a></li>'; navigation[3] = '</ul>'; navigation[4] = '</div><!-- close tab navigation -->'; function show(i) { (x in i) { document.write(i[x] + '\n') } } i have created above function in javascript menubar need call menubar in html file.
i recommend use document.createelement instead of using document write, , array of string.
secondly recommend initialize arrays using [] literal instead of using array construct.
this:
var arr = [1,2,3]; //like var arr2 = new array(1,2,3,4); // not recommended the code below should work want do.
var navigation = document.createelement('div'); navigation.id = 'menu'; navigation.innerhtml = '<ul><li>' + '<li><a href="../about_us.htm">aboutus</a></li>' + '</ul></li>'; document.body.appendchild(navigation); there few ways can call html:
- wrap in
<script></script>tag @ bottom of page - put in function set call onload
- add other trigger in html.
personally recommend putting in function , adding onload event.
javascript:
window.onload = appendnavigation; function appendnavigation() { var navigation = document.createelement('div'); navigation.id = 'menu'; navigation.innerhtml = '<ul><li>' + '<li><a href="../about_us.htm">aboutus</a></li>' + '</ul></li>'; document.body.appendchild(navigation); } html:
<!doctype html> <html> <head>...</head> <body> <script src="/script.js"></script> </body> </html> if want working example @ jsfiddle: https://jsfiddle.net/d1r43w33/
although should aware when used outside of jsfiddle, must include script link in html.
