这是一个使用闭包函数的计算器操作符

结果块中的

在将其转换为整数后也显示为NaN。

Mathamatical.js //封闭内容

var pradeep=(function(){
    result = 0; sum_is=sub_is=mul_is=divn_is=0; 
    function manupulation(x,y){
        sum_is = getsumValues(x,y);
        sub_is = getsubValues(x,y);
        mul_is = getmulValues(x,y);
        divn_is = getdivnValues(x,y);
        return result[sum_is,sub_is,mul_is,divn_is];
    }
    function getsumValues(x,y){
        var sum_is = x+y;
        return result[0]; 
    }
    function getsubValues(x,y){
        var sub_is = x-y;
        return sub_is;
    }
    function getmulValues(x,y){
        var mul_is = x*y;

        manupulation_value : function(x,y){
            return manupulation(x,y);

我的第二个js文件

function calculate_operations(){
    var details = {}
    details.Firstvalue = document.querySelector("#fnumber").value;
    details.SecondValue = document.querySelector("#snumber").value;
    details.Firstvalue = parseInt(details.Firstvalue);
    details.SecondValue = parseInt(details.SecondValue);
    details.result = 0;
    //details.selectedOperation = document.querySelector("operation")
    details.showdetails = function(){
        console.log(pradeep);
        document.querySelector("#numberF").innerText = details.Firstvalue;
        document.querySelector("#numberS").innerText = details.SecondValue;
        function operationsMathematical(){
            if (document.querySelector("#operation".value == "")) {
                document.querySelector("#sel_operation").innerText = +"No operation selected";
            }
            if (document.querySelector("#operation").value== "add") {
                document.querySelector("#sel_operation").innerHTML =+details.Firstvalue +"+" +details.SecondValue ;
                details.result= pradeep.manupulation_value(details.Firstvalue,details.SecondValue);
                //console.log(details.Firstvalue,details.SecondValue);
                details.result=parseInt(pradeep.manupulation_value(result[0]));
                document.querySelector("#result_block").innerHTML = +details.result;

            }

        }
        operationsMathematical();
    }
    //details.result= pradeep.manupulation_value(details.Firstvalue,details.SecondValue);

Answer 1

更改了文件。这应该工作

np.concatenate([a[1:, :2], a[:0:-1, [2,0]]], axis=1)
# array([[ 2.1,  2.2,  4.3,  4.1],
#        [ 3.1,  3.2,  3.3,  3.1],
#        [ 4.1,  4.2,  2.3,  2.1]])

您的第二个文件有错误。

var pradeep=(function(){
    // No need of these variables result = 0; sum_is=sub_is=mul_is=divn_is=0; 
    function manupulation(x,y){
        var sum_is = getsumValues(x,y); //use var otherwise global scope is used
        var sub_is = getsubValues(x,y);
        var mul_is = getmulValues(x,y);
        var divn_is = getdivnValues(x,y);
        return [sum_is,sub_is,mul_is,divn_is];
    }
    function getsumValues(x,y){
        var sum_is = x+y;
        return sum_is; 
    }
    function getsubValues(x,y){
        var sub_is = x-y;
        return sub_is;
    }
    function getmulValues(x,y){
        var mul_is = x*y;
        return mul_is;
    }
    function getdivnValues(x,y){
        var divn_is = x/y;
        return divn_is;
    }
    return{
        manupulation_value : function(x,y){
            return manupulation(x,y);
        }
    }
})();

使用闭包来计算数学运算......？
