如何使一个于Ajax.Autocompleter执行的请求没有打字？ [英] How do I make an Ajax.Autocompleter perform a request without typing?

问题描述

我使用的是Scriptaculous的的于Ajax.Autocompleter与不同的过滤器进行搜索。

I'm using scriptaculous's Ajax.Autocompleter for a search with different filters.

http://github.com/madrobby/scriptaculous/wikis/ajax-aut​​ocompleter

过滤器都要求我的动态数据传递到autocompleter，我已经成功地学会从以下链接做。

The filters are requiring me to pass data into the autocompleter dynamically, which I've successfully learned to do from the following link.

现在，我有多个过滤器和一个搜索框。我如何获得autocompleter发出请求的没有的输入到输入，而是通过点击一个新的过滤器？

Now, I have multiple filters and one search box. How do I get the autocompleter to make the request without typing into the input, but by clicking a new filter?

下面是一个使用案例澄清。页面加载，有多个过滤器（只是与onclicks链路），并附加了autocompleter一个输入字段。我键入查询和autocompleter请求被执行。然后，我点击不同的过滤器，和我想用相同的查询，但不同的滤波器执行的另一请求。

Here's a use case to clarify. The page loads, there are multiple filters (just links with onclicks), and one input field with the autocompleter attached. I type a query and the autocompleter request is performed. Then, I click on a different filter, and I'd like another request to be performed with the same query, but different filter.

或者更简洁地说，我怎么让autocompleter执行请求的当我想这取决于输入来触发它的的，而不是？

Or more succinctly, how do I make the autocompleter perform the request when I want, instead of depending on typing to trigger it?

推荐答案

我还发现，activate（）方法很好工作。下面是我的示例code ....

I also found that the activate() method worked great. Here is my sample code....

<script type="text/javascript">
    /*<![CDATA[*/

    var autocomp1 = new Ajax.Autocompleter("search", "AjaxResultsListPlaceholder", "ajaxServerSideSearchHandler.php", {
            frequency: 1,
            minChars: 10,
            indicator: "AjaxWorkingPleaseWaitPlaceholder",
            } );


    /*]]>*/
</script>

<form id="theform">
    <input type="text" id="search" name="search" value="" />
    <input type="button" id="btn_search" name="btn_search" value="Search" onclick="autocomp1.activate();" />
    <div id="AjaxWorkingPleaseWaitPlaceholder" style="display: none; border: 1px solid #ffaaaa;">
    </div>
    <div id="AjaxResultsListPlaceholder" style="display: none;; border: 1px solid #aaffaa;">
    </div>

</form>
