1,页面中点击一个按钮，清空file框中的值：
注：<input name=” fileText” type=”file”/>
onClick=" fileText.select();document.selection.clear();"
2,页面中，让一个img的图片显示小手的标志
<img style=”cursor:pointer” src=”” />
3,页面中直接用DAO层的方法（注解）
<s:bean name="com.dingxun.tiku.dao.impl.TopicCarDaoImpl" id="topicCarDao"></s:bean>
<s:set name="topicSize" value="#topicCarDao.findTopicSize(topicId,#session.userbean.frontUserId)"></s:set>
<span class="carCheckBox<s:property value='topicId'/>">
<s:if test="#topicSize>0">
<input type="checkbox" class="checkTopic" id="checkTopic" name="checkTopic" value="<s:property value='topicId'/>" disabled>
</s:if>
<s:else> <input type="checkbox" name="checkTopic" value="<s:property value='topicId'/>" > </s:else>
</sapn>
页面中的jquery中的使用
function addToCar(tId){
var topicId = tId;
$.ajax({
type: "POST",
url: "<%=pathstep1 %>/ManualPaperAjaxAction/save.action",
data: "topicId="+topicId,
cache: false,
success: function(msg){
$('.carMes'+tId).html("<input name='Submit' type='button' value='已入试题篮' disabled='disabled' class='btOrange'>");
$('.carCheckBox'+tId).html('<input type="checkbox" name="checkTopic" value="+tId+" disabled>');
},
error: function (XMLHttpRequest, textStatus, errorThrown)
{
alert(errorThrown);
alert(textStatus);
}
});}
4，页面中显示文本，可以直接截取：
例子：<s:if test="topicInfo.topic.length()>80">
<s:property value="topicInfo.topic.substring(0,80)" /><strong>. . . . . .</strong>
</s:if>

6,拿出页面的一个数组，或者同名的全部值。然后再动态的改变页面中的某些值。比如动态改变题目个数、分数。
function countSum(){ //计算试卷题目总数
var countSum = 0;//题目总数
$(".order").each(function(i){//从class=”order”中拿出所有的值，然后循环
countSum = 0
countSum =i+1;
});
$('#topicSum').html(countSum);
}
function scoreSum(){ //计算试卷题目总分
var scoreSum = 0;//试卷总分
$(".scoresList").each(function(i){
scoreSum += this.value*1;
});
$('#topicScoreSum').html(scoreSum);
}
<span class="order" > </span>-------------------
