Javascript 警報未出現
[英]Javascript alerts not coming up
問題描述
我正在嘗試驗證名字和姓氏字段，如果它們不是至少 3 個字符長，則發送警報。 如果名字和姓氏都不是至少 3 個字符，如果其中一個或另一個沒有至少 3 個字符，我也想要一個警報。 我曾嘗試將這些功能分開，但它們不會在一個警報中一起出現。 謝謝！

一些小問題，但大多是錯別字
function stringlength(inputtxt1, minlength1, maxlength1, inputtxt2, minlength2, maxlength2) { var field1 = inputtxt1; var mnlen1 = minlength1; var mxlen1 = maxlength1; var field2 = inputtxt2; var mnlen2 = minlength2; var mxlen2 = maxlength2; console.log(field1,mnlen1,mxlen1) if (field1.length < mnlen1 || field1.length > mxlen1) { alert("First name must be 3 characters or more"); return false; } else if (field2.length < mnlen2 || field2.length > mxlen2) { alert("Last name must be 3 characters or more"); return false; } else if ((field1.length < mnlen1 || field1.length > mxlen1) && (field2.length < mnlen2 || field2.length > mxlen2)) { alert("First name must be 3 characters or more\nLast name must be 3 characters or more "); return false; } else { return true; } } stringlength("ts",3,5,"tccs",3,5)
Javascript函數既記錄又顯示彈出警報？
