DIV CSS 佈局教程網

微博如火如荼，大家都選擇用微博帶來社會化流量，順便推廣產品和網站，幾乎所有的網站都有分享到代碼，但是還有一種更快捷的分享方式，javascript就可以實現將選定內容輕松分享到新浪微博和騰訊微博，效果圖如下：

將選中的內容分享到新浪微博，騰訊微博實現js代碼如下：

<STYLE>
.img_sina_share {
DISPLAY: none; CURSOR: pointer; POSITION: absolute
}
.img_qq_share {
DISPLAY: none; CURSOR: pointer; POSITION: absolute
}
</STYLE>
<IMG
class=img_sina_share id=imgSinaShare title=將選中內容分享到新浪微博
src="http://www.phpddt.com/usr/themes/dddefault/images/sina.gif">
<IMG
class=img_qq_share id=imgQqShare title=將選中內容分享到騰訊微博
src="http://www.phpddt.com/usr/themes/dddefault/images/qq.gif">
<SCRIPT>
var eleImgShare = document.getElementById("imgSinaShare"); /
var eleImgShare2 = document.getElementById("imgQqShare"); 
 
var $miniBlogShare = function(eleShare,eleShare2,eleContainer) { //實現方法
var eleTitle = document.getElementsByTagName("title")[0];
eleContainer = eleContainer || document;
var funGetSelectTxt = function() { //獲取選中文字
var txt = "";
if(document.selection) {
txt = document.selection.createRange().text; // IE
} else {
txt = document.getSelection();
}
return txt.toString();
};
eleContainer.onmouseup = function(e) { //限定容器若有文字被選中
e = e || window.event;
var txt = funGetSelectTxt(), sh = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop || 0;
var left = (e.clientX - 40 < 0) ? e.clientX + 20 : e.clientX - 40, top = (e.clientY - 40 < 0) ? e.clientY + sh + 20 : e.clientY + sh - 40;
if (txt) {
eleShare.style.display = "inline";
eleShare.style.left = left + "px";
eleShare.style.top = top + "px";
eleShare2.style.display = "inline";
eleShare2.style.left = left + 30 + "px";
eleShare2.style.top = top + "px";
} else {
eleShare.style.display = "none";
eleShare2.style.display = "none";
}
};
eleShare.onclick = function() { //點擊新浪微博圖標
var txt = funGetSelectTxt(), title = (eleTitle && eleTitle.innerHTML)? eleTitle.innerHTML : "未命名頁面";
if (txt) {
window.open('http://v.t.sina.com.cn/share/share.php?title=' + txt + ' ' + title + '&url=' + window.location.href + '','微博分享','width=700, height=580, top=320, left=180, toolbar=no, menubar=no, scrollbars=no, location=yes, resizable=no, status=no');
}
};
eleShare2.onclick = function() { //點擊騰訊微博圖標
var txt = funGetSelectTxt(), title = (eleTitle && eleTitle.innerHTML)? eleTitle.innerHTML : "未命名頁面";
if (txt) {
window.open( 'http://v.t.qq.com/share/share.php?title=' + encodeURIComponent(txt + ' ' + title + ' ') + '&url=' + window.location.href + '','微博分享','width=700, height=580, top=320, left=180, toolbar=no, menubar=no, scrollbars=no, location=yes, resizable=no, status=no');
}
};
}(eleImgShare,eleImgShare2);
</SCRIPT>

將以上的代碼黏貼到你想要進行內容分享的頁面，要注意的是，最好不要放在header.php或者footer.php這樣網站所有內容都進行分享，而我只是放在文章頁面！

以上就是js實現將選中內容分享到新浪或騰訊微博的詳細代碼，希望對大家學習javascript程序設計有所幫助。
