因为商城项目的需求，自己写了一个小例子。
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> input { display: block; margin: 1em; } button { margin: 1em; color:#fff; background:#999; border:none; } </style> <script src="../library/zepto.all.min.js"></script> </head> <body> <input type="text" class="test" id="test1"/> <input type="text" class="test" id="test2"/> <input type="text" class="test" id="test3"/> <button id="testBtn">button</button> <script> var test1 = document.getElementById(‘test1‘); var test2 = document.getElementById(‘test2‘); var test3 = document.getElementById(‘test3‘); var testBtn = document.getElementById(‘testBtn‘); var flag = false; var arr = []; arr.push(test1); arr.push(test2); arr.push(test3); arr.forEach(function (ele) { ele.addEventListener(‘blur‘, function () { flag = arr.every(function (obj) { return obj.value !== ‘‘; }); if(flag){ testBtn.style.backgroundColor = ‘green‘; } else { testBtn.style.backgroundColor = ‘#999‘; } }, false); }); </script> </body> </html>
