我在表单中有三个部分,第一个包含一个输入,第二个包含三个输入,第三个包含一个复选框。如何
每次我必须只有一个活动部分。
我所做的不是解决方案,因为第二部分存在问题。如果本节中只有一个输入为空,则启用所有其他输入。任何人都可以帮助我。 谢谢,抱歉我的英文
document.getElementById("client").onblur = function () {
if (this.value.length > 0) {
document.getElementById("FirstName").disabled=true;
document.getElementById("LastName").disabled=true;
document.getElementById("Email").disabled=true;
document.getElementById("standard").disabled=true;
}else {
document.getElementById("FirstName").disabled=false;
document.getElementById("LastName").disabled=false;
document.getElementById("Email").disabled=false;
document.getElementById("standard").disabled=false;
}
}
document.getElementById("FirstName").onblur = function () {
if (this.value.length > 0) {
document.getElementById("client").disabled=true;
document.getElementById("standard").disabled=true;
}else {
document.getElementById("client").disabled = false;
document.getElementById("standard").disabled = false;
}
}
document.getElementById("LastName").onblur = function () {
if (this.value.length > 0) {
document.getElementById("client").disabled=true;
document.getElementById("standard").disabled=true;
}else {
document.getElementById("client").disabled = false;
document.getElementById("standard").disabled = false;
}
}
document.getElementById("Email").onblur = function () {
if (this.value.length > 0) {
document.getElementById("client").disabled=true;
document.getElementById("standard").disabled=true;
}else {
document.getElementById("client").disabled = false;
document.getElementById("standard").disabled = false;
}
}
document.getElementById("standard").onblur = function () {
if (this.checked) {
document.getElementById("client").disabled=true;
document.getElementById("FirstName").disabled=true;
document.getElementById("LastName").disabled=true;
document.getElementById("Email").disabled=true;
}else {
document.getElementById("client").disabled=false;
document.getElementById("FirstName").disabled=false;
document.getElementById("LastName").disabled=false;
document.getElementById("Email").disabled=false;
}
}

听起来你可能想要尝试焦点监听器而不是on Blur监听器。

当我输入所有字段的值时,第二个元素似乎有效。看起来它正在检查输入的长度。
