Build your own web2.0 apps

Zoho Creator by AdventNet is a webbased interface that allows you to CREATE programs. The whole thing has a rich AJAX built interface that has a familiar look and feel for users known to AJAX apps in general and other zoho releases specifically, such as the zoho planner (reviewed by me before). Creation of an application such as a form is easy. The editor does everything for you - you just provide the content. As soon as the application is built you can easily create one or more views where you can see the results, sorted as you like and there's also room for reporting. The app looks great for creating datacollection applications such as crm apps and helpdesk (ticketing) systems. The best thing is to obtain a link to the application you built to embed it in your website. A nice feature fro spreadsheet-tigers : You can import them to create applications.

ajaxfileupload

jQuery is a fast, concise, JavaScript Library

that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages.


This AjaxFileUpload Plugin is a hacked version of Ajaxupload plugin created by yvind Saltvik, which is really good enought for normal use. Its idea is to create a iframe and submit the specified form to it for further processing.

In this hacked version, it submits the specified file type of input element only rather than an entire form



How to use it?

1. include jquery.js & ajaxfileupload.js javascript files
2. create a function to be fired when the upload button clicked.
e.g.
function ajaxFileUpload()
{
//starting setting some animation when the ajax starts and completes
$("#loading")
.ajaxStart(function(){
$(this).show();
})
.ajaxComplete(function(){
$(this).hide();
});

/*
prepareing ajax file upload
url: the url of script file handling the uploaded files
fileElementId: the file type of input element id and it will be the index of $_FILES Array()
dataType: it support json, xml
secureuri:use secure protocol
success: call back function when the ajax complete
error: callback function when the ajax failed

*/
$.ajaxFileUpload
(
{
url:'doajaxfileupload.php',
secureuri:false,
fileElementId:'fileToUpload',
dataType: 'json',
success: function (data, status)
{
if(typeof(data.error) != 'undefined')
{
if(data.error != '')
{
alert(data.error);
}else
{
alert(data.msg);
}
}
},
error: function (data, status, e)
{
alert(e);
}
}
)

return false;

}
