验证后提交 Javascript 表单

Question

该脚本的主要功能是我希望的那样:当未选择单选复选框时发出警报。但是，如果选择了所有按钮，我需要提交表单......这就是我挂断的地方。现在，如果选择了所有字段和按钮，那么我仍然会收到 var AlertMsg 的警报。有什么想法吗？

function submitform() {
    var sizeChoice = ""
    var size = document.store.on1.length
    var fontChoice = ""
    var len = document.store.on2.length
    var materialChoice = ""
    var material = document.store.on3.length
    var treatmentChoice = ""
    var treatment = document.store.on4.length
    var a = document.forms["store"]["item_name"].value;
    var alertMsg = "Please Choose a:"
    for(i = 0; i < size; i++) {
        if(document.store.on1[i].checked) {
            sizeChoice = document.store.on1[i].value
        }
    }
    for(i = 0; i < len; i++) {
        if(document.store.on2[i].checked) {
            fontChoice = document.store.on2[i].value
        }
    }
    for(i = 0; i < material; i++) {
        if(document.store.on3[i].checked) {
            materialChoice = document.store.on3[i].value
        }
    }
    for(i = 0; i < treatment; i++) {
        if(document.store.on4[i].checked) {
            treatmentChoice = document.store.on4[i].value
        }
    }
    if(a == null || a == "") alertMsg += "\n" + "Name" + "\n";
    if(sizeChoice == "") {
        alertMsg += "Size" + "\n"
    }
    if(fontChoice == "") {
        alertMsg += "Font" + "\n"
    }
    if(materialChoice == "") {
        alertMsg += "Material" + "\n"
    }
    if(treatmentChoice == "") {
        alertMsg += "Treatment" + "\n"
    } {
        alert(alertMsg)
    };
    return false;
    document.forms["form"].submit();
};

您在提交表单之前有一个返回。这可能是问题的一部分。

此外，您在最后的 if 语句中缺少 else。
