方法1：遍历页面元素
/*清空form id：表单id*/ function clearform（id）{var objid = document.getelementbyid（id）; if（objid == undefined）{return;} for（var i = 0; i <objid.elements.lention.lention.length.length; i ++）{if（objid.elements [i] .type = = ".type = =" "" "" "objid.el "";} else if（objid.elements [i] .type == "password"）{objid.elements [i] .value = "";} else if（objid.elements [i] .type == "radio"）{objid.elements [i] checked = fals;} els（i] {objid.elements [i] .checked = false;} else if（objid.elements [i] .type == "select-one"）{objid.elements [i] .options [0] .elected = true;} else if（objid.elements [i] .type = " objid.elements [i] .options.length; j ++）{objid.elements [j] .elected = false;}} {// //objid.elements [i] .select(/// //document.selection.clearect.clear(///// ""; // ff（包括3.5）//} //}}}方法2：使用リセット按钮
页面中增加
<！ - 用来清空表单数据 - > <入力タイプ= "reset" name = "reset" style = "display：none;" />
触发リセット事件
$（ "input [type = reset]"）。トリガー（ "クリック"）;
