使用iframe嵌套页面，并在页面中添加导航功能，iframe只适应高度
效果图如下图
主页面
主页面js
//让iframe只适应高度
function iFrameHeights() {
var ifm = document.getElementById("rightIframePage");
ifm.height = 0;
var subWeb = document.frames ? document.frames["rightIframePage"].document : ifm.contentDocument;
if (ifm != null && subWeb != null) {
ifm.height = subWeb.body.scrollHeight;
ifm.parentElement.style.height = subWeb.body.scrollHeight + "px";
}
}
iframe页面a.jsp
导航js 代码
$(document).ready(function() {
//让iframe回到顶部
parent.scrollTo(0,0);
initTitleNavigationEvent("broker");
// 主页面滚动时，模仿position: fixed;这种功能，因为position: fixed;对于iframe子页面来说不起作用
$(parent.window).scroll(function() {
$('#sideToolbar').css({
top : $(parent.window).scrollTop() + 116
});
// 滚动父页面滚动条时相应的切换导航位置，即让导航跟随页面滚动
scrollNavlWithHtmlScroll("broker");
});
});
/**
* 初始化事件
*/
function initTitleNavigationEvent(name){
// 添加单击事件
$("#sideCatalog-catalog dl dd a").bind('click',{name : name}, function(e) {
var id = e.target.id.substring(e.target.id.lastIndexOf("-") + 1, e.target.id.length);
quickPositioning(e.data.name + id);
$("#sideCatalog-catalog dl dd").removeClass("highlight");
$(this).parent().addClass("highlight");
});
// 滚动到顶部
$("#sideToolbar-up").bind('click', function(e) {
parent.scrollTo(0,0);
});
// 显示或隐藏导航
$("#sideCatalogBtn").bind('click', function(e) {
if ($(this).hasClass('sideCatalogBtnDisable')) {
$("#sideCatalog-sidebar").show();
$("#sideCatalog-updown").show();
$("#sideCatalog-catalog").show();
$("#sideCatalogBtn").removeClass("sideCatalogBtnDisable");
} else {
$("#sideCatalog-sidebar").hide();
$("#sideCatalog-updown").hide();
$("#sideCatalog-catalog").hide();
$("#sideCatalogBtn").addClass("sideCatalogBtnDisable");
}
});
}
/**
* 滚动到指定位置
* @param id 位置id
*/
function quickPositioning(id){
document.getElementById(id).scrollIntoView();
}
/**
* 导航跟随页面滚动
*/
function scrollNavlWithHtmlScroll(name){
// 滚动条距离顶端值
var wst = $(parent.window).scrollTop();
// 加循环
for (var i = 1; i // 判断滚动条位置
if ($("#" + name + i).offset().top // 清除高亮
$('#sideCatalog-catalog dl dd').removeClass("highlight");
// 给当前导航加高亮
$("#sideToolbar-item-0-" + i).addClass("highlight");
} else {
break;
}
}
