我找到了通过文件搜索输入将 CSV 读入表格的代码,但无法弄清楚如何让它在页面加载时自动读取 CSV 文件。
以下是googlecode中用于表格的 CSV 代码。
$(document).ready(function() {
if(isAPIAvailable()) {
$('#files').bind('change', handleFileSelect);
}
});
function isAPIAvailable() {
// Check for the various File API support.
if (window.File && window.FileReader && window.FileList && window.Blob) {
// Great success! All the File APIs are supported.
return true;
} else {
// source: File API availability - http://caniuse.com/#feat=fileapi
// source: <output> availability - http://html5doctor.com/the-output-element/
document.writeln('The HTML5 APIs used in this form are only available in the following browsers:<br />');
// 6.0 File API & 13.0 <output>
document.writeln(' - Google Chrome: 13.0 or later<br />');
// 3.6 File API & 6.0 <output>
document.writeln(' - Mozilla Firefox: 6.0 or later<br />');
// 10.0 File API & 10.0 <output>
document.writeln(' - Internet Explorer: Not supported (partial support expected in 10.0)<br />');
// ? File API & 5.1 <output>
document.writeln(' - Safari: Not supported<br />');
// ? File API & 9.2 <output>
document.writeln(' - Opera: Not supported');
return false;
}
}
function handleFileSelect(evt) {
var files = evt.target.files; // FileList object
var file = files[0];
// read the file metadata
var output = ''
output += '<span style="font-weight:bold;">' + escape(file.name) + '</span><br />\n';
output += ' - FileType: ' + (file.type || 'n/a') + '<br />\n';
output += ' - FileSize: ' + file.size + ' bytes<br />\n';
output += ' - LastModified: ' + (file.lastModifiedDate ? file.lastModifiedDate.toLocaleDateString() : 'n/a') + '<br />\n';
// read the file contents
printTable(file);
// post the results
$('#list').append(output);
}
function printTable(file) {
var reader = new FileReader();
reader.readAsText(file);
reader.onload = function(event){
var csv = event.target.result;
var data = $.csv.toArrays(csv);
var html = '';
for(var row in data) {
html += '<tr>\r\n';
for(var item in data[row]) {
html += '<td>' + data[row][item] + '</td>\r\n';
}
html += '</tr>\r\n';
}
$('#contents').html(html);
};
reader.onerror = function(){ alert('Unable to read ' + file.fileName); };
}
