我有这个弹出窗口正在由javascript使用px中心。我需要这个盒子来响应,所以我怎样才能调整脚本来计算百分比而不是px。可能吗?这个当前的代码允许我产生一个自动弹出,但它也有一个脚本,它使用px来对齐弹出窗口。这不响应。如何使脚本以百分比工作?
function toggle(div_id) {
var el = document.getElementById(div_id);
if (el.style.display == 'none') { el.style.display = 'block';}
else {el.style.display = 'none';}
}
function blanket_size(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportheight = window.innerHeight;
} else {
viewportheight = document.documentElement.clientHeight;
}
if ((viewportheight > document.body.parentNode.scrollHeight) && (viewportheight > document.body.parentNode.clientHeight)) {
blanket_height = viewportheight;
} else {
if (document.body.parentNode.clientHeight > document.body.parentNode.scrollHeight) {
blanket_height = document.body.parentNode.clientHeight;
} else {
blanket_height = document.body.parentNode.scrollHeight;
}
}
var blanket = document.getElementById('blanket');
blanket.style.height = blanket_height + 'px';
var popUpDiv = document.getElementById(popUpDivVar);
popUpDiv_height=blanket_height/2-187.5;//200 is half popup's height
popUpDiv.style.top = popUpDiv_height + 'px';
}
function window_pos(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportwidth = window.innerHeight;
} else {
viewportwidth = document.documentElement.clientHeight;
}
if ((viewportwidth > document.body.parentNode.scrollWidth) && (viewportwidth > document.body.parentNode.clientWidth)) {
window_width = viewportwidth;
} else {
if (document.body.parentNode.clientWidth > document.body.parentNode.scrollWidth) {
window_width = document.body.parentNode.clientWidth;
} else {
window_width = document.body.parentNode.scrollWidth;
}
}
var popUpDiv = document.getElementById(popUpDivVar);
window_width=window_width/2-250;//200 is half popup's width
popUpDiv.style.left = window_width + 'px';
}
function popup(windowname) {
blanket_size(windowname);
window_pos(windowname);
toggle('blanket');
toggle(windowname);
}
究竟是你想实现什么目标?当你点击一个按钮或者某个东西时,屏幕居中显示一个模式对话框? – element11
这是一个自动弹出这个当前的代码做到这一点,但也需要你使用px来定位框 –
