the data export method using jquery and php.
Javascript function for data export
function table2csv(oTable, exportmode, tableElm) { var csv = ''; var headers = []; var rows = []; // Get header names $(tableElm+' thead').find('th').each(function() { var $th = $(this); var text = $th.text(); var header = '"' + text + '"'; // headers.push(header); // original code if(text != "") headers.push(header); // actually datatables seems to copy my original
"); tmp.innerHTML = html; return tmp.textContent||tmp.innerText; }
Function supports exporting all data and current page data
// export only what is visible right now (filters paginationapplied)$('#export_visible').click(function(event) { var oTable; oTable= $('#spdata').dataTable(); event.preventDefault(); table2csv(oTable, 'visible', '#spdata'); }) // export all table data $('#expor

Actually DataTables seems to copy I original headers so there ist a amount of TH cell

A real example: predict the future traffic based on the past traffic of a company's servers.
Procedure:
1. Read data:
The server volume is recorded as a csvfile web_traffic.csv in the following format:
1 22722nan31386413655148861337718838228391335101025111139121477
In the data, the first column is the number of hours, and the second column is the access volume for that hour. Use scipy to read a scipy-defined array for scientific computing (the Code is as follows ):
import scipy as
python in computationally intensive areas? Because Python can easily assign a numeric calculation task to these underlying extensions in C or FORTRAN. Among them, NumPy and scipy are the representatives.NumPy provides a number of effective data structures, such as arrays, and SCIPY provides many algorithms to handle these arrays. Whether it's matrix manipulation, linear algebra, optimization problems, clustering, or even fast Fourier transforms, the Toolbox can meet the requirements.Read-In Dat
call the functions named Add in the JS function, pass in two parameters, and receive the return value with Varret. After the Invoke2 call succeeds, Varret gets the return value of 30.However, you can only accept one return value at a time. What if you want to accept more than one return value at a time?We can let JS return an array or object in JS.When the JS function return an array or an object, the Varret on the VC side will accept a IDispatch interface representing the object. We still use
