最近需要一个简单的瀑布流效果，所以网上找了一个，修改了部分代码
1、轻量代码，压缩2kb。
2、适用宽度自适应布局。瀑布流列由css控制。（先加入空列，获取宽度，删除空列，根据总宽计算列数。）
wall.js
"use strict"; (function ($) { $.fn.jaliswall = function (options) { this.each(function () { var defaults = { item: ‘.wall-item‘, columnClass: ‘.wall-column‘, resize: true }; var prm = $.extend(defaults, options); var container = $(this); var items = container.find(prm.item); var elemsDatas = []; var columns = []; var nbCols = getNbCols(); init(); function init() { nbCols = getNbCols(); recordAndRemove(); print(); if (prm.resize) { $(window).resize(function () { if (nbCols != getNbCols()) { nbCols = getNbCols(); setColPos(); print(); } }); } } function getNbCols() { var instanceForCompute = false; if (container.find(prm.columnClass).length == 0) { instanceForCompute = true; container.append(‘<div class=\‘‘ + parseSelector(prm.columnClass) + ‘\‘></div>‘); } var colWidth = container.find(prm.columnClass).outerWidth(true); var wallWidth = container.innerWidth(); if (instanceForCompute) container.find(prm.columnClass).remove(); return Math.round(wallWidth / colWidth); } function recordAndRemove() { items.each(function (index) { var item = $(this); elemsDatas.push({ content: item.html(), class: item.attr(‘class‘), href: item.attr(‘href‘), id: item.attr(‘id‘), colid: index % nbCols }); item.remove(); }); } function setColPos() { for (var i in elemsDatas) { elemsDatas[i].colid = i % nbCols; } } function parseSelector(selector) { return selector.slice(1, selector.length); } function print() { var tree = ‘‘; for (var i = 0; i < nbCols; i++) { tree += ‘<div class=\‘‘ + parseSelector(prm.columnClass) + ‘\‘></div>‘; } container.html(tree); for (var i in elemsDatas) { var html = ‘‘; var content = elemsDatas[i].content != undefined ? elemsDatas[i].content : ‘‘; var href = elemsDatas[i].href != href ? elemsDatas[i].href : ‘‘; var classe = elemsDatas[i].class != undefined ? elemsDatas[i].class : ‘‘; var id = elemsDatas[i].id != undefined ? elemsDatas[i].id : ‘‘; if (elemsDatas[i].href != undefined) { html += ‘<a ‘ + getAttr(href, ‘href‘) + ‘ ‘ + getAttr(classe, ‘class‘) + ‘ ‘ + getAttr(id, ‘id‘) + ‘>‘ + content + ‘</a>‘; } else { html += ‘<div ‘ + getAttr(classe, ‘class‘) + ‘ ‘ + getAttr(id, ‘id‘) + ‘>‘ + content + ‘</a>‘; } var tHeight = container.children(prm.columnClass).eq(0).height(),childIndex = 0; for (var j = 0; j < nbCols; j++) { if(container.children(prm.columnClass).eq(j).height() < tHeight){ childIndex = j; } } container.children(prm.columnClass).eq(childIndex).append(html); } } function getAttr(attr, type) { return attr != undefined ? type + ‘=\‘‘ + attr + ‘\‘‘ : ‘‘; } }); return this; }; }(jQuery));
压缩后代码
eval(function(p,a,c,k,e,d){e=function(c){return(c<a?"":e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!‘‘.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return‘\\w+‘};c=1;};while(c--)if(k[c])p=p.replace(new RegExp(‘\\b‘+e(c)+‘\\b‘,‘g‘),k[c]);return p;}(‘"Z 13";(4($){$.Y.X=4(D){p.E(4(){2 S={b:\‘.G-b\‘,8:\‘.G-10\‘,s:y};2 5=$.11(S,D);2 6=$(p);2 H=6.q(5.b);2 3=[];2 12=[];2 c=m();J();4 J(){c=m();K();u();e(5.s){$(W).s(4(){e(c!=m()){c=m();M();u()}})}}4 m(){2 w=19;e(6.q(5.8).O==0){w=y;6.U(\‘<l d=\\\‘\‘+t(5.8)+\‘\\\‘></l>\‘)}2 L=6.q(5.8).1a(y);2 I=6.1c();e(w)6.q(5.8).F();o 1b.18(I/L)}4 K(){H.E(4(Q){2 b=$(p);3.15({f:b.h(),d:b.g(\‘d\‘),7:b.g(\‘7\‘),9:b.g(\‘9\‘),T:Q%c});b.F()})}4 M(){r(2 i R 3){3[i].T=i%c}}4 t(v){o v.14(1,v.O)}4 u(){2 x=\‘\‘;r(2 i=0;i<c;i++){x+=\‘<l d=\\\‘\‘+t(5.8)+\‘\\\‘></l>\‘}6.h(x);r(2 i R 3){2 h=\‘\‘;2 f=3[i].f!=n?3[i].f:\‘\‘;2 7=3[i].7!=7?3[i].7:\‘\‘;2 C=3[i].d!=n?3[i].d:\‘\‘;2 9=3[i].9!=n?3[i].9:\‘\‘;e(3[i].7!=n){h+=\‘<a \‘+k(7,\‘7\‘)+\‘ \‘+k(C,\‘d\‘)+\‘ \‘+k(9,\‘9\‘)+\‘>\‘+f+\‘</a>\‘}16{h+=\‘<l \‘+k(C,\‘d\‘)+\‘ \‘+k(9,\‘9\‘)+\‘>\‘+f+\‘</a>\‘}2 N=6.z(5.8).A(0).P(),B=0;r(2 j=0;j<c;j++){e(6.z(5.8).A(j).P()<N){B=j}}6.z(5.8).A(B).U(h)}}4 k(g,V){o g!=n?V+\‘=\\\‘\‘+g+\‘\\\‘\‘:\‘\‘}});o p}}(17));‘,62,75,‘||var|elemsDatas|function|prm|container|href|columnClass|id||item|nbCols|class|if|content|attr|html|||getAttr|div|getNbCols|undefined|return|this|find|for|resize|parseSelector|print|selector|instanceForCompute|tree|true|children|eq|childIndex|classe|options|each|remove|wall|items|wallWidth|init|recordAndRemove|colWidth|setColPos|tHeight|length|height|index|in|defaults|colid|append|type|window|jaliswall|fn|use|column|extend|columns|strict|slice|push|else|jQuery|round|false|outerWidth|Math|innerWidth‘.split(‘|‘),0,{}))

其他。这里的其他宽度是480-640的宽度，可以根据实际调整。
