SpringMVC、jquery、tiles 和部分重新渲染
我正在尝试使用 spring mvc 3.1、tiles 2 和 jquery 对我的网站进行部分渲染。
这是我的 spring conf :
<beans:bean class="org.springframework.js.ajax.AjaxUrlBasedViewResolver">
<beans:property name="viewClass" value="org.springframework.js.ajax.tiles2.AjaxTilesView"/>
</beans:bean>
我的tiles conf :
<definition name="productSearch" extends="baseLayout">
<put-attribute name="mainSection">
<definition template="/WEB-INF/views/productSearch.jsp">
<put-attribute name="productSearchResults" value="/WEB-INF/views/productSearchResults.jsp" />
</definition>
</put-attribute>
</definition>
如您所见,有一个名为“productSearchResults”的嵌套属性。这是结果页面,我希望通过ajax重新渲染该页面。
我的控制器:
@RequestMapping(params = "search=true", value = "/", method = RequestMethod.POST)
public String searchHandler(@Valid final SearchFormBean searchformBean, final Model model) {
model.addAttribute("productsList", productsService.findProducts(searchformBean.getSearchCriteria()));
return "productsSearch";
}
我的jsps:
productSearch.jsp:
<form:form id="product-search-form" method="post" modelAttribute="productSearchFormBean">
<input type="hidden" name="search" value="" />
<form:input path="searchCriteria.name" />
// AND SOME OTHER FIELDS...
<button type="submit" onclick="this.form.search.value='true';">Search</button>
</form>
productSearchResults.jsp:
<div id="products-result">
<div id="search-results-info" class="section-content">
Order results :
<form:select path="searchCriteria.resultsSort">
<form:option value="orderByName">Name</form:option>
<form:option value="orderByDame">Date</form:option>
</form:select>
</div>
<div id="products-content" class="section-content">
<c:forEach var="product" items="${productsList}">
<article>
// PRODUCT INFORMATIONS DISPLAYED HERE...
</article>
</c:forEach>
</div>
</div>
最后是productSearch.jsp中包含的.js文件:
$('select[id="searchCriteria.resultsSort"]').change(function() {
$.ajax({
type : "POST",
url : "/myapp/product/search/",
data : "search=true&fragments=productSearchResults",
success : function(response) {
$("#search-results").html(response);
},
error : function(e) {
alert('Error : ' + e);
}
});
});
所以事情是这样的:每次我更改productSearchResults.jsp中的“searchCriteria.resultsSort”选择器值时页面,我希望重新加载结果图块(而不重新加载整个页面)。
使用上面给出的代码,我设法重新渲染整个页面(包括 html 标签...),而不仅仅是我感兴趣的部分。
关于如何实现我的目标有任何提示吗?真的有可能还是我误解了部分渲染原理?
I'm trying to do a partial rendering of my web site, using spring mvc 3.1, tiles 2, and jquery.
Here's my spring conf :
<beans:bean class="org.springframework.js.ajax.AjaxUrlBasedViewResolver">
<beans:property name="viewClass" value="org.springframework.js.ajax.tiles2.AjaxTilesView"/>
</beans:bean>
My tiles conf :
<definition name="productSearch" extends="baseLayout">
<put-attribute name="mainSection">
<definition template="/WEB-INF/views/productSearch.jsp">
<put-attribute name="productSearchResults" value="/WEB-INF/views/productSearchResults.jsp" />
</definition>
</put-attribute>
</definition>
As you see there's a nested attribute named "productSearchResults". This is the results page, and I want this page to be re-rendered via ajax.
My controller :
@RequestMapping(params = "search=true", value = "/", method = RequestMethod.POST)
public String searchHandler(@Valid final SearchFormBean searchformBean, final Model model) {
model.addAttribute("productsList", productsService.findProducts(searchformBean.getSearchCriteria()));
return "productsSearch";
}
My jsps :
productsSearch.jsp :
<form:form id="product-search-form" method="post" modelAttribute="productSearchFormBean">
<input type="hidden" name="search" value="" />
<form:input path="searchCriteria.name" />
// AND SOME OTHER FIELDS...
<button type="submit" onclick="this.form.search.value='true';">Search</button>
</form>
productSearchResults.jsp :
<div id="products-result">
<div id="search-results-info" class="section-content">
Order results :
<form:select path="searchCriteria.resultsSort">
<form:option value="orderByName">Name</form:option>
<form:option value="orderByDame">Date</form:option>
</form:select>
</div>
<div id="products-content" class="section-content">
<c:forEach var="product" items="${productsList}">
<article>
// PRODUCT INFORMATIONS DISPLAYED HERE...
</article>
</c:forEach>
</div>
</div>
and finally a .js file included in the productSearch.jsp :
$('select[id="searchCriteria.resultsSort"]').change(function() {
$.ajax({
type : "POST",
url : "/myapp/product/search/",
data : "search=true&fragments=productSearchResults",
success : function(response) {
$("#search-results").html(response);
},
error : function(e) {
alert('Error : ' + e);
}
});
});
So here's the thing : every time that I change the "searchCriteria.resultsSort" selector value in the productsSearchResults.jsp page, I want the results tile to be reloaded (without reloading the whole page).
With the code given above, I manage to re-render the whole page (including the html tag...) but not just the portion that interest's me.
Any hint on how to achieve my goal ? Is it really possible or I misunderstood the partial rendering principle ?

我发现出了什么问题,所以我正在回答我自己的问题...
我刚刚将 javascript 代码更改为:
现在它可以工作了!
由于部分重新渲染,一旦页面重新加载到屏幕,“searchCriteria.resultsSort”选择器似乎不再映射到表单,所以我还必须将此行添加到我的控制器中:
仅此而已!希望它能帮助其他人。
I found what was wrong, so I'm answering my own question...
I just changed the javascript code into this :
And now it works !
Beacause of the partial-re-rendering, it seems that the "searchCriteria.resultsSort" selector is no longer mapped to the form, once the page is reloaded to the screen, so I had also to add this line to my controller :
That's all ! Hope it helps other people.
