Question

我需要检查一个数组是否包含字符串值或数值。我在javascript中检查以下代码。但是下面的代码不起作用。

$(function() {
    var data = ["0", "1", "2"];
var isAlpha = false;
var alphabetRegex = /^[a-zA-Z]*$/; ///^[a-zA-Z ]*$/
arrayLen = data.length;
//checking if array is alphabet
while (--arrayLen) {
    if (alphabetRegex.test(data[arrayLen])) {
        isAlpha = true;
        break;
    }
}

if (isAlpha == true) { //this condition for alphabet sorting
    //......code here
} else { //this condition only for number values
    //code here
}

});

下面的代码对我有用。我已将if条件更改为

if (data[arrayLen].trim().match(/\D/)) {

而不是

if (alphabetRegex.test(data[arrayLen]))

完整代码：

$(function() {
var data = ["0", "1", "2"];
var isAlpha = false;
arrayLen = data.length;
//checking if array is alphabet
while (--arrayLen) {
    if (data[arrayLen].trim().match(/\D/)) {
        isAlpha = true;
        break; //break the loop if even single array value contains string
    }
}

if (isAlpha == true) { //this condition for alphabet sorting
    //......code here
} else { //this condition only for number values
    //code here
}
});

在javascript中检查数组值是字符串还是数字
