HomeBackend DevelopmentPHP Tutorialphp+ajax实时输入自动搜索匹配的方法_PHP

本文实例讲述了php+ajax实输入自动搜索匹配的方法分享给大家供大家参考。具体分析如下:

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:

代码如下:





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:

代码如下:

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[$uval]); 
    }            
    }else{//按下的不是t的时候,要把第二个首字母符合的内容添加到正常查询的数组中。 
    if(!emptyempty($narr) && !emptyempty($list)){//带The 的符合条件正常 本身也不空的时候。 
    $list = array_merge($narr,$list);//合并数组。 
    }else if(emptyempty($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:

代码如下:

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."); 
        } 
    } 
}

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
