在 Java EE 应用程序上，我有以下点击功能
function calculateK() {
var matD = "" + $('.dr1c1').val() + "__" + $('.dr1c2').val() + "__" + $('.dr1c3').val()
+ "__" + $('.dr2c1').val() + "__" + $('.dr2c2').val() + "__" + $('.dr2c3').val()
+ "__" + $('.dr3c1').val() + "__" + $('.dr3c2').val() + "__" + $('.dr3c3').val();
var h = '5';
var it = 0;
var cellB = '';
var cellJ = '';
var cellK = '';
for (it = 1; it < 5; it++) {
cellB = '.b' + it;
cellJ = '.jc' + it;
cellK = '.k' + it;
var bb1 = $(cellB + 'r1c1').val();
var bb2 = $(cellB + 'r1c2').val();
var bb3 = $(cellB + 'r2c1').val();
var bb4 = $(cellB + 'r2c2').val();
var bb5 = $(cellB + 'r3c1').val();
var bb6 = $(cellB + 'r3c2').val();
var jj = $(cellJ).val();
$.ajax({
url: '/M08CDECUStructuralOptimiser/ServletMatrix1?action=calculateJ',
data: {matrixB: "" + bb1 + "__" + bb2 + "__" + bb3 + "__" + bb4 + "__" + bb5 + "__" + bb6, matrixD: matD, valJ: jj},
dataType: "json",
success: function(response) {
$(cellK+'1').val(response[0]);
$(cellK+'2').val(response[1]);
$(cellK+'3').val(response[2]);
$(cellK+'4').val(response[3]);
$(cellK+'5').val(response[4]);
$(cellK+'6').val(response[5]);
$(cellK+'7').val(response[6]);
$(cellK+'8').val(response[7]);
$(cellK+'9').val(response[8]);
}
});
}
}
在小服务程序上
try {
if (action.compareTo("calculateJ") == 0) {
String matrixStringB = request.getParameter("matrixB");
String[] tempStringArray;
tempStringArray = matrixStringB.split("__");
double[][] array = {{Double.parseDouble(tempStringArray[0]), Double.parseDouble(tempStringArray[1])},
{Double.parseDouble(tempStringArray[2]), Double.parseDouble(tempStringArray[3])},
{Double.parseDouble(tempStringArray[4]), Double.parseDouble(tempStringArray[5])}};
Matrix b = new Matrix(array);
Matrix bT = b.transpose();
Matrix c = b.times(bT);
//System.out.println(Arrays.deepToString(c.getArray()));
String matrixStringD = request.getParameter("matrixD");
String[] tempStringArray2;
tempStringArray2 = matrixStringD.split("__");
double[][] arrayD = {{Double.parseDouble(tempStringArray2[0]), Double.parseDouble(tempStringArray2[1]), Double.parseDouble(tempStringArray2[2])},
{Double.parseDouble(tempStringArray2[3]), Double.parseDouble(tempStringArray2[4]), Double.parseDouble(tempStringArray2[5])},
{Double.parseDouble(tempStringArray2[6]), Double.parseDouble(tempStringArray2[7]), Double.parseDouble(tempStringArray2[8])}};
Matrix d = new Matrix(arrayD);
Matrix r1 = c.times(d);
String matrixStringJ = request.getParameter("valJ");
double valj = Double.parseDouble(matrixStringJ);
Matrix r2 = r1.times(valj);
double valh = 1.5;
Matrix r3 = r2.times(valh);
double[][] resultArray = r3.getArray();
double[] oneDArray = new double[resultArray.length * resultArray.length];
//Flatten 2D array to 1D array...
int s = 0;
for (int i = 0; i < resultArray.length; i++) {
for (int j = 0; j < resultArray.length; j++) {
oneDArray[s] = resultArray[i][j];
s++;
}
}
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json = gson.toJson(oneDArray);
//System.out.println(oneDArray.length);
System.out.println(Arrays.deepToString(r3.getArray()));
out.println(json);
}
} finally {
}
现在在控制台上我得到了所有 4 个数组并且有正确的值但是在站点上只有最后一个 k 值显示 k41,k42,.......k49
如何解决这个问题？
当我尝试将 js 循环限制为 <2 时，它会正确显示 k11、k12、......k19 值。
