Slimbox是轻量级的图片灯箱插件,以包裹图片img标签之外的a标签的rel属性为锚点,触发Slimbox()函数来展示效果!废话不多说

步骤一

先引入slimbox灯箱js库,具体代码如下:(2.05版)

(function(w){var E=w(window),u,f,F=-1,n,x,D,v,y,L,r,m=!window.XMLHttpRequest,s=[],l=document.documentElement,k={},t=new Image(),J=new Image(),H,a,g,p,I,d,G,c,A,K;w(function(){w("body").append(w([H=w('<div id="lbOverlay" />').click(C)[0],a=w('<div id="lbCenter" />')[0],G=w('<div id="lbBottomContainer" />')[0]]).css("display","none"));g=w('<div id="lbImage" />').appendTo(a).append(p=w('<div style="position: relative;" />').append([I=w('<a id="lbPrevLink" href="#" />').click(B)[0],d=w('<a id="lbNextLink" href="#" />').click(e)[0]])[0])[0];c=w('<div id="lbBottom" />').appendTo(G).append([w('<a id="lbCloseLink" href="#" />').click(C)[0],A=w('<div id="lbCaption" />')[0],K=w('<div id="lbNumber" />')[0],w('<div style="clear: both;" />')[0]])[0]});w.slimbox=function(O,N,M){u=w.extend({loop:false,overlayOpacity:0.8,overlayFadeDuration:400,resizeDuration:400,resizeEasing:"swing",initialWidth:250,initialHeight:250,imageFadeDuration:400,captionAnimationDuration:400,counterText:"Image {x} of {y}",closeKeys:[27,88,67],previousKeys:[37,80],nextKeys:[39,78]},M);if(typeof O=="string"){O=[[O,N]];N=0}y=E.scrollTop()+(E.height()/2);L=u.initialWidth;r=u.initialHeight;w(a).css({top:Math.max(0,y-(r/2)),width:L,height:r,marginLeft:-L/2}).show();v=m||(H.currentStyle&&(H.currentStyle.position!="fixed"));if(v){H.style.position="absolute"}w(H).css("opacity",u.overlayOpacity).fadeIn(u.overlayFadeDuration);z();j(1);f=O;u.loop=u.loop&&(f.length>1);return b(N)};w.fn.slimbox=function(M,P,O){P=P||function(Q){return[Q.href,Q.title]};O=O||function(){return true};var N=this;return N.unbind("click").click(function(){var S=this,U=0,T,Q=0,R;T=w.grep(N,function(W,V){return O.call(S,W,V)});for(R=T.length;Q<R;++Q){if(T[Q]==S){U=Q}T[Q]=P(T[Q],Q)}return w.slimbox(T,U,M)})};function z(){var N=E.scrollLeft(),M=E.width();w([a,G]).css("left",N+(M/2));if(v){w(H).css({left:N,top:E.scrollTop(),width:M,height:E.height()})}}function j(M){if(M){w("object").add(m?"select":"embed").each(function(O,P){s[O]=[P,P.style.visibility];P.style.visibility="hidden"})}else{w.each(s,function(O,P){P[0].style.visibility=P[1]});s=[]}var N=M?"bind":"unbind";E[N]("scroll resize",z);w(document)[N]("keydown",o)}function o(O){var N=O.which,M=w.inArray;return(M(N,u.closeKeys)>=0)?C():(M(N,u.nextKeys)>=0)?e():(M(N,u.previousKeys)>=0)?B():null}function B(){return b(x)}function e(){return b(D)}function b(M){if(M>=0){F=M;n=f[F][0];x=(F||(u.loop?f.length:0))-1;D=((F+1)%f.length)||(u.loop?0:-1);q();a.className="lbLoading";k=new Image();k.onload=i;k.src=n}return false}function i(){a.className="";w(g).css({backgroundImage:"url("+n+")",visibility:"hidden",display:""});w(p).width(k.width);w([p,I,d]).height(k.height);w(A).html(f[F][1]||"");w(K).html((((f.length>1)&&u.counterText)||"").replace(/{x}/,F+1).replace(/{y}/,f.length));if(x>=0){t.src=f[x][0]}if(D>=0){J.src=f[D][0]}L=g.offsetWidth;r=g.offsetHeight;var M=Math.max(0,y-(r/2));if(a.offsetHeight!=r){w(a).animate({height:r,top:M},u.resizeDuration,u.resizeEasing)}if(a.offsetWidth!=L){w(a).animate({width:L,marginLeft:-L/2},u.resizeDuration,u.resizeEasing)}w(a).queue(function(){w(G).css({width:L,top:M+r,marginLeft:-L/2,visibility:"hidden",display:""});w(g).css({display:"none",visibility:"",opacity:""}).fadeIn(u.imageFadeDuration,h)})}function h(){if(x>=0){w(I).show()}if(D>=0){w(d).show()}w(c).css("marginTop",-c.offsetHeight).animate({marginTop:0},u.captionAnimationDuration);G.style.visibility=""}function q(){k.onload=null;k.src=t.src=J.src=n;w([a,g,c]).stop(true);w([I,d,g,G]).hide()}function C(){if(F>=0){q();F=x=D=-1;w(a).hide();w(H).stop().fadeOut(u.overlayFadeDuration,j)}return false}})(jQuery);

步骤二

为包裹img标签的a标签添加rel=lightbox属性 作为钩子锚点!slimbox()函数触发灯箱效果。

// 灯箱函数
function slimbox_reload(){
    $(".main_post img").parent().attr({rel: "lightbox"});
    $("a[rel=lightbox]").slimbox();
}

slimbox_reload()就是重载函数了,放入初始化一次,放在ajax加载完成后一次。

步骤三

相应的CSS是必不可少的,否则也看不到效果。

/* SLIMBOX2 */
#lbOverlay{position:fixed;z-index:9999;left:0;top:0;width:100%;height:100%;background-color:#000;cursor:pointer;}
#lbCenter, #lbBottomContainer{position:absolute;z-index: 9999;overflow: hidden;background-color:#fff;}
#lbImage {position:absolute;left:0;top:0;border:6px solid #fff;background-repeat:no-repeat;}
#lbPrevLink,#lbNextLink{display: block;position: absolute;top:0;width:50%;outline:none;}
#lbPrevLink{left:0;}
#lbPrevLink:hover{background:transparent url(images/prevlabel.gif) no-repeat 0 15%;}
#lbNextLink{right:0;}
#lbNextLink:hover{background:transparent url(images/nextlabel.gif) no-repeat 100% 15%;}

That's All .
