本文章来给大家介绍php ajax实输入自动搜索匹配程序代码,希望此款程序对大家所有帮助了,第一种方法利用了jquery autocomplete,第二种使用了jquery ajax,其实两个都差不多。

最简单的办法我们就是直接使用jquery autocomplete方法了,如下在实例

html中

 代码如下 复制代码


本文目的是让 某个标题 带有 The 的不按字母t首字母搜索,而是按照第二个文字的首字母搜索。

比如 The Orbolg, 按T的时候不显示,按O的时候才显示。

下面是实现代码。我自己都晕晕的。测试是没有问题。

 代码如下 复制代码

public function gwquery(){
    if($_POST){
    $zm = $_POST['data'];
    $wzm = $zm."%";
    $b = M('Wpindexgw');
    if($zm!="t"){//获取的首字母不是t的时候
    $list1 = $b->where("gwstatus=1 and gwname like '%$zm%'")->order("time desc")->select();//查询
    $narr =array();
    foreach( $list1 as $key => $val){        
        $ct2 = explode(" ",$val['gwname']);//获取标题拆分成数组。
         $szm=strtolower(substr($ct2[1],0,1));  //获取首字母 并且小写
        if($ct2[0]=="The" && $szm==$zm){//如果第一个字符是The 并且第二个字母首字母和提交的相同,这里The 区分大小写。
        $narr[] = $val; //写入数组
        }   
    }
    }else{      //处理首字母是T的时候    ,不希望第一个字数The 的显示在列表里。
        $list1 = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();
    foreach( $list1 as $key => $val){        
        $ct2 = explode(" ",$val['gwname']);
        if($ct2[0]=="The"){
        $unnarr[] = $key;//获取符合条件的,要去掉的内容的数组标号。     
        }
         
    }   
             
}
    $list = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();//正常的查询。
    if($zm=="t"){//处理当首字母是t的时候 ,去掉上面查询得到的内容,也就是如果是The的时候 按T 不显示。
    foreach($unnarr as $uval){
        unset($list[$uval]);
    }           
    }else{//按下的不是t的时候,要把第二个首字母符合的内容添加到正常查询的数组中。
    if(!empty($narr) && !empty($list)){//带The 的符合条件正常 本身也不空的时候。
    $list = array_merge($narr,$list);//合并数组。
    }else if(empty($list)){//正常查询为空。则看是否有带The开头的,有则合并
    $list=array();
    $list = array_merge($narr,$list);   
    }
    }
    if($list){
    $this->ajaxReturn($list,'success',1);
    }else{
        $this->error("Bestiary not found.");
        }
    }
     
}

相比之前的代码:相差太多

 代码如下 复制代码

public function gwquery1(){//之前备份。。
    if($_POST){
    $zm = $_POST['data'];
    $wzm = $zm."%";
    $b = M('Wpindexgw');
    $list = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();
    //dump($list);
    if($list){
    $this->ajaxReturn($list,'success',1);
    }else{
        $this->error("Bestiary not found.");
        }
    }
     
}
