Example code for jQuery to achieve header fixed effect_jquery
1. Create a new js file jQuery_FixedTableHead.js
The content is as follows:
jQuery.fn.CloneTableHeader = function(tableId, tableParentDivId) {
var obj = document.getElementById("tableHeaderDiv" tableId);
if (obj) {
jQuery(obj).remove();
}
var browserName = navigator.appName;
var ver = navigator.appVersion;
var browserVersion = parseFloat(ver.substring(ver.indexOf("MSIE") 5, ver.lastIndexOf("Windows")));
var content = document.getElementById(tableParentDivId);
var scrollWidth = content.offsetWidth - content.clientWidth;
var tableOrg = jQuery("#" tableId)
var table = tableOrg.clone();
table.attr("id", "cloneTable");
var tableClone = jQuery(tableOrg).find("tr").each(function() {
});
var tableHeader = jQuery(tableOrg).find("thead");
var tableHeaderHeight = tableHeader.height();
tableHeader.hide();
var colsWidths = jQuery(tableOrg).find("tbody tr:first td").map(function() {
return jQuery(this).width();
});
var tableCloneCols = jQuery(table).find("thead tr:first td")
if (colsWidths.size() > 0) {
for (i = 0; i < tableCloneCols.size(); i ) {
if (i == tableCloneCols.size() - 1) {
if (browserVersion == 8.0)
tableCloneCols.eq(i).width(colsWidths[i] scrollWidth);
else
tableCloneCols.eq(i).width(colsWidths[i]);
} else {
tableCloneCols.eq(i).width(colsWidths[i]);
}
}
}
var headerDiv = document.createElement("div");
headerDiv.appendChild(table[0]);
jQuery(headerDiv).css("height", tableHeaderHeight);
jQuery(headerDiv).css("overflow", "hidden");
jQuery(headerDiv).css("z-index", "20");
jQuery(headerDiv).css("width", "100%");
jQuery(headerDiv).attr("id", "tableHeaderDiv" tableId);
jQuery(headerDiv).insertBefore(tableOrg.parent());
}
