JS Common Code Snippets

Some of the public JS that will be used recently will continue to be supplemented.

String extensions (function () {var fn = String.prototype;        Fn.format = function () {var args = arguments; Return This.replace (/\{(\d+) \}/g, function (M, i) {return args[i] | |        "";    }); }})();

String formatting "Name:{0},value:{1}". Format ("P0", "P1"): "Name:p0,value:p1"

JSON transform

(function (WD) {    var transform = function (oldobj, prefix, Subobjorvalue, includefunc) {        if (Subobjorvalue = = null) {            Oldobj[prefix] = null;      &N Bsp } else {            if (subobjorvalue instanceof Array) {                for (var i = 0; i < subobjorvalue.length; i++) {              & nbsp     var Newpex = prefix + "[" + i + "]";                    TR Ansform (Oldobj, Newpex, Subobjorvalue[i], Includefunc);               }  &NB Sp        } else if (typeof subobjorvalue = = = "Object") {            &NBSP ;   for (var name in Subobjorvalue) {                    if (subobjor Value.hAsownproperty (name)) {                        var Newobjpex = "";                        if (prefix.length = = = 0) {  &N Bsp                         NEWOBJPEX = name + "";    &N Bsp                  } else {              &N Bsp             Newobjpex = prefix + "." + name;                       }                        T Ransform (Oldobj, Newobjpex, Subobjorvalue[name], Includefunc);                &NB Sp  }               }           } else {                if (includefunc) {                &NBSP ;   Oldobj[prefix] = subobjorvalue;               } else {                    if (typeof subobjorvalue!== "function") {        &N Bsp               Oldobj[prefix] = subobjorvalue;                   }               }          & nbsp }       }   }    WD. Json.__transformtosimple = function (jsonobj, prefix, includefunc) {        if (!jsonobj) {  &nbs P         return null;       }        var obj = {};  &nbsp ;     transform (obj, prefix | | "", Jsonobj, Includefunc);nbsp       return obj;   };}) (window); The JSON in JS is converted to simple JSON, multiple levels of JSON, converted to only one level of JSON, easy to simulate form submission.

{"A": "V-1", "B": {"b-1": "V-b1", "b-2": "V-b2"}, "C": ["V-c1", "V-C2"]}

Converted to

{"A": "V-1", "b.b-1": "V-b1", "b.b-2": "V-b2", "c[0]": "V-c1", "c[1]": "V-C2"}

HTML encode or decode (function (wd) {    Wd.__htmlencode = function (str) {        return ("" + str). Replace (/&/g, "&amp;")            . Replace (/>/g, "&gt;")            . Replace (/</g, "&lt;")            . Replace (//g, "&nbsp;")            . replace (/\ '/g, "'")            . replace (/\ "/g," "& Amp;quot; ");    };    Wd.__htmldecode = function (str) {        return ("" + str). Replace (/&am P;amp;/g, "&")            . Replace (/&gt;/g, ">")         &NBSP ;   Replace (/&lt;/g, "<")            . Replace (/&nbsp;/g, "")     &N Bsp       replace (/'/g, "\ '")            . Replace (/&quot;/g, "\"); &nbsP  };}) (window);

HTML encoding, the special symbols in the HTML code, to prevent interference damage to normal HTML.
