How to replace url parameters with regular JS
这次给大家带来JS的正则怎么替换url参数,JS正则替换url参数的注意事项有哪些,下面就是实战案例,一起来看一下。
具体代码如下所示:
/* 定义替换对象键值 */ var setReferArgs = function(){ var referArgs = new Object(); referArgs['#userID\#'] = userId; referArgs['\#userName\#'] = userName; return referArgs; } /* 替换URL的参数 */ var replaceUrlParams = function(url){ var actualUrl = ""; var referArgs = setReferArgs(); for(var key in referArgs){ var e = eval('/'+ key +'/g'); actualUrl = url.replace(e,referArgs[key]); url = actualUrl; } return actualUrl; }
栗子:
“http://10.0.0.250:8088/test?uesrID=#userID#” 替换成对应数值 “http://10.0.0.250:8088/test?uesrID=12345”;
“http://10.0.0.250:8088/test/#userID#” 替换成对应数值 “http://10.0.0.250:8088/12345”;
延伸:
js使用正则表达式从url中获取参数值
//从url中获取参数值 function getvl(name) { var reg = new RegExp("(^|\\?|&)"+ name +"=([^&]*)(\\s|&|$)", "i"); if (reg.test(location.href)) return unescape(RegExp.$2.replace(/\+/g, " ")); return ""; }; var code = getvl("code");

C++ parameter type safety checking ensures that functions only accept values of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.

Reference parameters in C++ functions (essentially variable aliases, modifying the reference modifies the original variable) and pointer parameters (storing the memory address of the original variable, modifying the variable by dereferencing the pointer) have different usages when passing and modifying variables. Reference parameters are often used to modify original variables (especially large structures) to avoid copy overhead when passed to constructors or assignment operators. Pointer parameters are used to flexibly point to memory locations, implement dynamic data structures, or pass null pointers to represent optional parameters.
