javascript 实现table 行折叠的例子

//firefox ,如果是ie 用block 替代

function doToggleRows(idTrToDisplay) {
var trID = document.getElementById(idTrToDisplay);
var img = document.getElementById(parseInt(idTrToDisplay) + 90000);

if(trID.style.display=="none") {
trID.style.display ="table-row";

img.src = "images/index.jpg";
} else {
trID.style.display="none";

img.src = "images/background_plus.jpg";
}
} 

for(var i = 0;i<a.length;i++){

if(a[i].style.display=="none") {
a[i].style.display ="table-row";
} else { a[i].style.display="none"; }
}

doToggleRows('Brick404348')

Html里面:

javascript:doToggleRows(''... ... ...'')
