我已经使用 javascript 在页面加载时创建了一个可缩放的表格。默认情况下,表格的可见性是隐藏的。当我在 IE 中最小化/最大化页面时,浏览器使隐藏的表格可见。任何人都可以帮助我解决这个问题。
创建可滚动表的javascript如下
/* Scrollable table */
function setScrollableTableHeight(name,maxrows)
{
var count;
var arrObj = document.getElementsByName(name);
for(count=0;count<arrObj.length;count++)
{
ScrollableTable(arrObj[0], maxrows);
}
}
// set Body width to screen width
function setBodyWidth()
{
objBody = document.getElementsByTagName('body');
objBody[0].style.width = screen.width - 40;
var objDivs = document.getElementsByTagName('div');
for(var i=0;i<objDivs.length;i++)
{
if(objDivs[i].className == "OuterPanel")
{
if(screen.width < 980)
objDivs[0].style.width = 980 - 42;
else
objDivs[0].style.width = screen.width - 42;
break;
}
}
}
function ScrollableTable (tableEl, maxRows, tableWidth) {
var tableHeight = 25 + maxRows * 25;
var numRows = 0;
this.initIEengine = function () {
if (this.tableEl.parentElement.clientHeight - this.tableEl.offsetHeight < 0) {
this.tableEl.style.width = this.newWidth - this.scrollWidth +'px';
}
if (this.thead) {
var trs = this.thead.getElementsByTagName('tr');
for (x=0; x<trs.length; x++) {
trs[x].style.position ='relative';
trs[x].style.setExpression("top", "this.parentElement.parentElement.parentElement.scrollTop + 'px'");
}
}
if (this.tfoot) {
var trs = this.tfoot.getElementsByTagName('tr');
for (x=0; x<trs.length; x++) {
trs[x].style.position ='relative';
trs[x].style.setExpression("bottom", "(this.parentElement.parentElement.offsetHeight - this.parentElement.parentElement.parentElement.clientHeight - this.parentElement.parentElement.parentElement.scrollTop) + 'px'");
}
}
eval("window.attachEvent('onresize', function () { document.getElementById('" + this.tableEl.id + "').style.visibility = 'hidden'; document.getElementById('" + this.tableEl.id + "').style.visibility = 'visible'; } )");
};
this.initFFengine = function () {
var headHeight = (this.thead) ? this.thead.clientHeight : 0;
var footHeight = (this.tfoot) ? this.tfoot.clientHeight : 0;
var bodyHeight = this.tbody.clientHeight;
this.tbody.setAttribute("id", "dynamicScrollParentfirefox");
var trs = this.tbody.getElementsByTagName('tr');

var tds;
if (bodyHeight >= (this.newHeight - (headHeight + footHeight))) {
for (x=0; x<trs.length; x++) {
tds = trs[x].getElementsByTagName('td');
tds[tds.length-1].style.paddingRight += this.scrollWidth + 'px';
}
}
var cellSpacing = (this.tableEl.offsetHeight - (this.tbody.clientHeight + headHeight + footHeight)) / 4;
this.tbody.style.height = (this.newHeight - (headHeight + cellSpacing * 2) - (footHeight + cellSpacing * 2)) + 'px';
};
this.tableEl = tableEl;
this.scrollWidth = 16;
this.originalHeight = this.tableEl.clientHeight;
this.originalWidth = this.tableEl.clientWidth;
/* modified by rmv */
if(parseInt(tableHeight) > this.originalHeight && this.originalHeight!=0)
tableHeight = this.originalHeight;
/* modified by rmv ends*/
this.newHeight = parseInt(tableHeight);
this.newWidth = tableWidth ? parseInt(tableWidth) : this.originalWidth;
this.tableEl.removeAttribute('height');
var loverflowParent = document.createElement('div');
loverflowParent.setAttribute("id","dynamicScrollParent");
this.containerEl = this.tableEl.parentNode.insertBefore(loverflowParent, this.tableEl);
this.containerEl.appendChild(this.tableEl);
this.containerEl.style.height = this.newHeight + 'px';
this.containerEl.style.width = this.newWidth + 'px';
var thead = this.tableEl.getElementsByTagName('thead');
this.thead = (thead[0]) ? thead[0] : null;
var tfoot = this.tableEl.getElementsByTagName('tfoot');
this.tfoot = (tfoot[0]) ? tfoot[0] : null;
var tbody = this.tableEl.getElementsByTagName('tbody');
this.tbody = (tbody[0]) ? tbody[0] : null;
if (!this.tbody) return;
if (document.all && document.getElementById && !window.opera) this.initIEengine()
if (!document.all && document.getElementById && !window.opera) this.initFFengine()
}
