問(wèn)題：在index.html 中，iframe 引入son.html，在son.html 中如何點(diǎn)擊某個(gè)操作，實(shí)現(xiàn)屏蔽整個(gè)頁(yè)面，并彈出要顯示的層？
準(zhǔn)備： index.html son.html
思路：
一：index.html中iframe引入son.html ，
<!-- 右側(cè)iframe開(kāi)始 -->
<div id="resDiv" class="resDiv">
<iframe name="res" class="iframestyle" allowtransparency="true" src="son.html" frameborder="0" scrolling="no"></iframe>
</div>
<!-- 右側(cè)iframe結(jié)束 -->
二： index.html的body部分中添加屏蔽層和內(nèi)容展示層
<!--彈出的登錄頁(yè)面層-->
<div id="mapLayer" style="display: none; " >
<input type="button" value="關(guān)閉" onclick="closeMap()" />
</div>
<!--屏蔽層，用來(lái)透明的屏蔽整個(gè)頁(yè)面-->
<div id="mapBgLayer" style="position:absolute; display: none;"></div>
三：index.html 中設(shè)置div的樣式和實(shí)現(xiàn)打開(kāi)關(guān)閉層的方法
<style type="text/css">
#BgLayer {
background: #939393 none repeat scroll 0 0;
height:100%;
width:100%;
left:0;
top:0;
filter: alpha(opacity=80); /* IE */
-moz-opacity: 0.8; /* Moz + FF */
z-index: 10000;
}
#Layer {
width: 400px;
height: 400px;
margin: -180px 0 0 -170px;
left: 50%;
top: 50%;
position: absolute;
background: #FFF;
z-index: 10001;
border: 1px solid #1B5BAC;
}
</style>
<script type="text/javascript">
/*顯示頁(yè)面*/
function showDiv) {
var bg = document.getElementById("BgLayer");
var con = document.getElementById("Layer");
//var w = document.documentElement.clientWidth; //網(wǎng)頁(yè)可見(jiàn)區(qū)域?qū)?
//var h = document.documentElement.clientHeight;//網(wǎng)頁(yè)可見(jiàn)區(qū)域高
var w = document.body.scrollWidth; //網(wǎng)頁(yè)正文全文寬
var h = document.body.scrollHeight; //網(wǎng)頁(yè)正文全文高
// alert(w+"-"+h);
bg.style.display = "";
bg.style.width = w + "px";
bg.style.height = h + "px";
con.style.display = "";
}
/*關(guān)閉*/
function closeDiv() {
var bg = document.getElementById("BgLayer");
var con = document.getElementById("Layer");
bg.style.display = "none";
con.style.display = "none";
}
</script>
四：son.html 中某個(gè)操作調(diào)用父頁(yè)面方法
<a href="javascript:void(0)" onclick="parent.window.showDiv()">查看</a>
