修改一个已经做好的系统,参数获取方式看不懂,请大神指教
页面提交到Action处理后
结尾部分参数代码是这样写的
echo '{"code":"0","giftPath":"' . $smallIcon . '","giftStyle":"' . $giftinfo['giftStyle'] . '","giftGroup":"' . $giftinfo['sid'] . '","giftType":"' . $giftinfo['giftType'] . '","toUserNo":"' . $emceeinfo['curroomnum'] . '","isGift":"0","giftLocation":"[]","giftIcon":"' . $giftinfo['giftIcon'] . '","giftSwf":"' . $giftinfo['giftSwf'] . '","toUserId":"' . $_REQUEST['toid'] . '","toUserName":"' . $emceeinfo['nickname'] . '","userNo":"' . $_SESSION['roomnum'] . '","giftCount":"' . $_REQUEST['count'] . '","userId":"' . $_SESSION['uid'] . '","giftName":"' . $giftinfo['giftname'] . '","userName":"' . $_SESSION['nickname'] . '","giftId":"' . $giftinfo['id'] . '"}';exit;
然后处理参数是在JS里完成的
var obj_box=data["ct"]; //这里不明白这个data["ct"]代表什么,查找整个项目也找不到相关代码obj_box=obj_box.replace(/\+/g,"%20");obj_box=evalJSON(decodeURIComponent(obj_box));var giftIcon=obj_box.giftIcon,giftNum=obj_box.giftCount,giftName=obj_box.giftName,giftimg='',isGift=obj_box.isGift || 0,ugood=obj_box["userNo"],uid=obj_box["userId"],uname=decodeURIComponent(obj_box["userName"]),cugood=this.chatgnum(obj_box["userNo"]),tougood=obj_box["toUserNo"],touid=obj_box["toUserId"],touname=decodeURIComponent(obj_box['toUserName']),tocugood=this.chatgnum(obj_box["toUserNo"]),gifttop=parseInt($('#gift_history li').size()) || 0;
上面这里也不明白,obj_box.giftIcon 和obj_box["userName"] 是一样的么?
最后,最大的问题来了,我在ACTION末端参数中加了一个参数,在ACTION里测试是有数值的,但是就是传不到JS里,不知道哪里出的问题
回复讨论(解决方案)
zjcoin这个就是自己加的参数
echo '{"code":"0","zjcoin":"' . $zjcoin . '","giftPath":"' . $smallIcon . '","giftStyle":"' . $giftinfo['giftStyle'] . '","giftGroup":"' . $giftinfo['sid'] . '","giftType":"' . $giftinfo['giftType'] . '","toUserNo":"' . $emceeinfo['curroomnum'] . '","isGift":"0","giftLocation":"[]","giftIcon":"' . $giftinfo['giftIcon'] . '","giftSwf":"' . $giftinfo['giftSwf'] . '","toUserId":"' . $_REQUEST['toid'] . '","toUserName":"' . $emceeinfo['nickname'] . '","userNo":"' . $_SESSION['roomnum'] . '","giftCount":"' . $_REQUEST['count'] . '","userId":"' . $_SESSION['uid'] . '","giftName":"' . $giftinfo['giftname'] . '","userName":"' . $_SESSION['nickname'] . '","giftId":"' . $giftinfo['id'] . '"}';
var zjcoin = obj_box["zjcoin"];//或者var zjcoin = obj_box.zjcoin;都无法获得值,提示未定义
这个php代码是ajax里后台向页面返回值的,在前台取json的值,看看js 的ajax是怎么取json的值就OK

能给一段正常json取值的代码么?我好对比一下。
在这段代码中,唯一看到跟取值有关的就是一句 var obj_box=data["ct"]; 这个data从哪来的 "ct"又代表什么,完全没有头绪
查了一些json的资料,例如:
function showJSON() { var user = { "username":"andy", "age":20, "info": { "tel": "123456", "cellphone": "98765"}, "address": [ {"city":"beijing","postcode":"222333"}, {"city":"newyork","postcode":"555666"} ] } alert(user.username); alert(user.age); alert(user.info.cellphone); alert(user.address[0].city); alert(user.address[0].postcode); user.username = "Tom"; alert(user.username); }
上例代码中,至少还有一个var user={ ... } 来存储json的代码,但是直接{...}这样编写的话,又该如何取值?

遍历获取
user[0].username
5楼的朋友没明白我的问题,
我这样说吧
在 thinkphp3.1的框架下
tpl中的 show.html 页面中进行了一些动作的提交,
提交到了lib中的showAction.class.php的其中一个方法sendMsg()代码如下
public funciton sendMsg()
{
//处理代码....忽略...
echo '{"code":"0","msg":"message1"}'; //这一段就是返回给Html信息的代码了,直接echo{参数...}
exit;
}
取值的时候,是在Javascript中的
var obj_box=data["ct"];
按照原来的代码,
obj_box.code 或者 obj_box["code"]都能取到值,可是我自己手动新增一个参数的话,就无法取值了,查过在action中是有值的,那么就是传输中出的问题,不知道大家有没有用过这种编写方式?
你自己增加的参数是怎么写的?
你自己增加的参数是怎么写的?
原先的action中的代码是
public funciton sendMsg()
{
//处理代码....忽略...
echo '{"code":"0","giftPath":"' . $smallIcon . '"......}';
exit;
}
增加参数后代码是
public funciton sendMsg()
{
//处理代码....忽略...
echo '{"code":"0", “zjcoin”:"'.$zjcoin.'","giftPath":"' . $smallIcon . '"......}';//红色的部分是增加的参数
exit;
}
在JS中,其他的参数可以用obj_box[""]来获取,可我自己添加的这个参数就是取不到,数值是有的,添加到数据库都看到值了。
又有了新的发现,另外一个js文件中
var GiftCtrl={ sendGift:function(){ var url="/index.php/Show/show_sendGift/eid/"+_show.emceeId+"/toid/"+GiftCtrl.gift_to_id+"/count/"+giftNum+"/gid/"+GiftCtrl.gift_id+"/t/"+Math.random(); var tmpgid=GiftCtrl.gift_id; GiftCtrl.clearGiftCfg(); $.getJSON(url,function(json){ if(json){ if(json.code==0){ GiftCtrl.gift_to_id=_show.emceeId; $('#giftto').html(_show.emceeNick); Chat.getUserBalance();//用户秀币更新 Dom.$swfId("flashCallChat")._chatToSocket(0, 2, '{"_method_":"sendGift","giftPath":"' + json.giftPath + '","giftStyle":"' + json.giftStyle + '","giftGroup":"' + json.giftGroup + '","giftType":"' + json.giftType + '","toUserNo":"' + json.toUserNo + '","isGift":"' + json.isGift + '","giftLocation":"' + json.giftLocation + '","giftIcon":"' + json.giftIcon + '","giftSwf":"' + json.giftSwf + '","toUserId":"' + json.toUserId + '","toUserName":"' + json.toUserName + '","userNo":"' + json.userNo + '","giftCount":"' + json.giftCount + '","userId":"' + json.userId + '","giftName":"' + json.giftName + '","userName":"' + json.userName + '","giftId":"' + json.giftId + '","zjcoin":"' + json.zjcoin + '"}');//这一段参数的顺序跟action中的顺序一样,末尾也加了zjcoin,结果还是无法获取 }}
最后那一段参数的顺序跟action中的顺序一样,我在末尾也加了zjcoin,结果还是无法获取

请指教?
终于知道原因了,原来参数传递还要通过一个swf文件, 网上下了几个能编辑swf代码的工具,能打开修改,但是一保存就弹出错误,不知道哪位大神有这样的工具,能编辑swf里面代码的工具

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
