JS参数传递,该如何解决
JS参数传递
现用Smarty做网站,想把在html页面中JS计算出来的变量fee提交到一个php处理页面去,用语句
document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee=fee";
在php中获取:
$fee=empty($_GET['fee'])?'':trim($_GET['fee']);
不过就是传递不过来,请问各位大虾正解如何?(JS中代码如下)
------解决方案--------------------
确实对新手来讲由于缺少必要的条理逻辑,所以只能用简单的传值方式来实现页面间值得传递,由于我也是新手了所以也只能说说我的困惑,我用js获取本页的文本结点然后通过异步请求将值传递到后台页面,然后打开后台php页面发现传递过来的值不可以直接运用,就是本身后台页面就是用来显示的,显示的东西和传递过来的值密切相关。怎么才能将上个页面传递过来的值直接用于显示呢?
------解决方案--------------------
你的代码还是用代码格式贴出来吧,这样看的很不舒服捏!
------解决方案--------------------
你最好打开编译后的文件,看看
document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee=fee";
变成了什么
------解决方案--------------------
document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee="+fee;

In order to optimize Go function parameter passing performance, best practices include: using value types to avoid copying small value types; using pointers to pass large value types (structures); using value types to pass slices; and using interfaces to pass polymorphic types. In practice, when passing large JSON strings, passing the data parameter pointer can significantly improve deserialization performance.

In a multi-threaded environment, function parameter passing methods are different, and the performance difference is significant: passing by value: copying parameter values, safe, but large objects are expensive. Pass by reference: Passing by reference is efficient, but function modifications will affect the caller. Pass by constant reference: Pass by constant reference, safe, but restricts the function's operation on parameters. Pass by pointer: Passing pointers is flexible, but pointer management is complex, and dangling pointers or memory leaks may occur. In parallel summation, passing by reference is more efficient than passing by value, and passing by pointer is the most flexible, but management is complicated.

In the Go language, there are two main ways to pass function parameters: value passing: passing a copy of the variable will not affect the original variable in the calling code. Pointer passing: Passing the address of a variable allows the function to directly modify the original variable in the calling code.

PHP functions can pass values through parameters, which are divided into pass by value and pass by reference: pass by value: modification of parameters within the function will not affect the original value; pass by reference: modification of parameters within the function will affect the original value. In addition, arrays can also be passed as parameters for operations such as calculating the sum of data.

There are two ways to pass parameters in PHP: call by value (the parameter is passed as a copy of the value, modification within the function does not affect the original variable) and passing by reference (the address of the parameter is passed, modification within the function will affect the original variable), when the original variable needs to be modified Use reference passing when calculating the shopping cart total price, which requires reference passing to calculate correctly.

Guide to Golang formal parameter requirements: parameter passing methods, value passing and address passing. In the process of learning the Golang programming language, it is very important to understand the parameter passing methods and the concepts of value passing and address passing. This article will delve into the formal parameter requirements in Golang, including the difference between parameter passing methods, value passing and address passing, and provide specific code examples to help readers better understand. 1. Parameter passing methods In Golang, there are two methods of parameter passing for functions: passing by value and passing by address. Pass by value (pass a copy): When the function is called, the actual

The function pointer is used as a parameter passing mechanism in C++: the function pointer is passed as a constant pointer, a copy is created during the passing process, the received function formal parameter points to the copy, and the dereferenced copy can call the underlying function.

In Go, function maps can be passed as parameters of functions, providing code reuse and customization capabilities: Create a function map: use the map[string]interface{} type, with the function name as the key and the function itself as the value. Pass as parameter: Use the funcMap type in the function parameter list to accept a function map. Execute a function: Retrieve the function from the function map via the reflect package and call it with variable arguments. Practical case: Function mapping can be passed to the template engine to dynamically execute template functions at runtime.
