我尝试了项目中的代码来更改选择框的大小:
<strong>Result Div :</strong>
<div id="formResult" class="result ui-widget-content ui-corner-all">Submit form bellow.</div>
<strong>Topics Div :</strong>
<div id="topics" class="result ui-widget-content ui-corner-all"></div>
<s:form id="form" action="echo" theme="simple" cssClass="yform">
<fieldset>
<legend>Select Box as Autocompleter</legend>
<div class="type-select">
<label for="echo">Echo: </label>
<sj:autocompleter
id="customers"
name="echo"
list="%{customers}"
listValue="name"
listKey="id"
selectBox="true"
selectBoxIcon="true"
onChangeTopics="autocompleteChange"
onFocusTopics="autocompleteFocus"
onSelectTopics="autocompleteSelect"
cssStyle="width:100%;"
/>
</div>
<div>
<sj:submit
targets="formResult"
value="AJAX Submit"
indicator="indicator"
button="true"
/>
<img id="indicator" src="images/indicator.gif" alt="Loading..." style="display:none"/>
</div>
</fieldset>
</s:form>
<br/>
但它不起作用。我不知道这段代码有什么问题。
