js控制获得焦点与失去焦点样式
function focusInput(focusClass, normalClass) { var elements = document.getElementsByTagName("input"); for (var i = 0; i < elements.length; i++) { if (elements[i].type != "button" && elements[i].type != "checkbox" && elements[i].type != "radio" && elements[i].type != "submit" && elements[i].type != "reset") { elements[i].className = normalClass; elements[i].onblur = function() { this.className = normalClass; }; elements[i].onfocus = function() { this.className = focusClass; }; } } } //页面一加载就应用这种样式 window.onload = function () { focusInput('input50_focus', 'input50'); focusTextarea('textarea50_focus','textarea50'); } //创建第一个td var td = tr.insertCell(1); td.innerHTML = "<input type="hidden" name="summaryId"+num+"" id="summaryId"+num+ "" /> <input type="hidden" name="personInChargeId"+num+"" id="personInChargeId"+num+""/>"+ " <input type="text" name="personInChargeName"+num+"" id="personInChargeName"+num+"" />"; focusInput('input50_focus','input50');td.style.cssText="BORDER-BOTTOM: #4a75ce 1px solid";
td.className="样式"; //虽然我玉树临风，风流倜傥，有广阔的胸怀和强健的臂腕，有杨过的冷酷、韦小宝的多情、郭靖的纯朴、张无忌的优柔、乔峰的豪爽，但是你若是喜欢我可以跟我说的呀，我一定会认真考虑的一 一！
