我一直在寻找很多东西并尝试新事物，但没有一个适合我。
场景：用户有一个搜索表单，用于搜索有多个复选框，无线电，输入字段的文件。
现在，用户可以选择搜索条件，即按文件类型（pdf，doc，图像，关键字等等）或按关键字（元数据）或/和文件标题搜索。
数据源是xml。
我正在使用ajax，regExp来匹配。但是不知道获得正确结果并显示它们需要什么。我可以知道：
1。这种方法适用于存在大量数据的情况（大型xml包含超过10,000个条目）。
2。需要什么来获得正确的结果并显示它们。
到目前为止，我已经被困住了......
提前致谢....

答案 0 :(得分：0)
几个问题：
您的脚本存在语法错误，请查看Firebug或IE Developer工具并进行修复。
我认为您没有按预期使用“查找”。 Find将“获取当前匹配元素集中的每个元素的后代，由选择器，jQuery对象或元素过滤”。
您可能需要考虑以下解决方案：
- ＆GT;根据用户选择过滤文件名或关键字元素（使用查找）
- ＆GT; while循环匹配搜索关键字的元素文本值
- ＆GT;将匹配的项添加到数组
- ＆GT;循环遍历数组并将结果显示给用户
