html表单相关问题

Question

嘿我想重置表单，但我不知道如何。我的意思是我应该在哪里添加事件。我希望在我提交表单之后或在iframe中加载结果之前，应该重置该表单。

<div class="mainArea">
        <iframe id="uploadTarget" name="uploadTarget" src="OnlineExam?q=allQuestions" 
        style="width:15%;height:100%;border:1px solid #fff; float:left;" >          
        </iframe>       
        <div id="questionArea">
        <h1 class="headingClassC">Please Input Questions: </h1>
        <br class="clearFormatting"/>
        <span class="instructions"><br/>
        1. You can use HTML tags to format your text
        <br/>
        2. To Edit a previously inserted question please click on the question no. shown on the left side.<br/>
        3. You can attach an image file with the question which will be used as reference. <br/>
        </span>     
        <form action="OnlineExam?q=saveQuestion" method="post" target="uploadTarget" id="inputQuestionForm">
        <fieldset>
        <legend>Question</legend>
        <textarea class="questionArea" id="question" name="question">Enter Question.</textarea>
        <br class="clearFormatting"/>               
        <input class="optionsInput" value="optionA" name="optionA" onfocus = "clearValues('optionA')" onblur = "setValues('optionA')"/>
        <br class="clearFormatting"/>

        <input class="optionsInput" value="optionB" name="optionB" onfocus = "clearValues('optionB')" onblur = "setValues('optionB')"/>
        <br class="clearFormatting"/>

        <input class="optionsInput" value="optionC" name="optionC" onfocus = "clearValues('optionC')" onblur = "setValues('optionC')"/>
        <br class="clearFormatting"/>

        <input class="optionsInput" value="optionD" name="optionD" onfocus = "clearValues('optionD')" onblur = "setValues('optionD')"/>
        <br/>
        <input class="optionsInput" value="answer" name="answer" onfocus="clearValues('answer')" onblur="setValues('answer')"/>     
        <input type="submit" value="Save"/>
        <input type="reset" value="Cancel" />
        <button style="display: none" onclick="return deleteQuestion()" >Delete</button>        
        </fieldset>
        </form>
        <br/><br/>
        Once you have finished inputing question <a href="OnlineExam?q=ready">click here</a> to go back.

        </div>      
    </div>

误读了你的问题...

您需要使用javascript重置表单。 这是一个良好的开端：

Resetting a multi-stage form with jQuery

你应该在iframe中添加一个脚本来调用父框架，并在iframe加载后清除表单。

您显然无法在提交活动之前清除表单。
