window.history.back(-1)
window.history.back(); window.history.forward() window.history.go(-1)
javascript:history.go(-1)和javascript:history.back(-1)
go(-1): 返回上一页, 原页面表单中的内容会丢失; back(-1): 返回上一页, 原页表表单中的内容会保留.
go(-1): 返回上一页, 原页面表单中的内容会丢失; back(-1): 返回上一页, 原页表表单中的内容会保留. <input type=button value=刷新 onclick="window.location.reload()"> <input type=button value=前进 onclick="window.history.go(1)"> <input type=button value=后退 onclick="window.history.go(-1)"> <input type=button value=前进 onclick="window.history.forward()"> <input type=button value=后退 onclick="window.history.back()"> 后退+刷新<input type=button value=后退 onclick="window.history.go(-1);window.location.reload()">history.back()是会上一页i=1history.go(i)去指定的某页如果是history.go(0)那就是刷新这两个属于JS代码,相当于IE的前进、后退功能。具体的用处就要看什么时候需要这个就用上。比如用户注册时的验证是后台验证,不符合要求的时候就可以用这个,可以最大限度保证用户少重复输入数据。例如:载入页面:function onLoadPage(){if(event.srcElement.tagName=="SPAN"){oFrame=top.window.middle.frames[2];oTxt=event.srcElement.innerText;switch(oTxt){ case "前 进":oFrame.history.go(1);case "后 退":oFrame.history.back();case "刷 新":oFrame.location.reload();}}}
如果按钮的ID是LinkButton1
