1,根据具体标签判断
function JudgesubmitForm() {
var judjeWs = false;
var judjeAt = false;
var judjeWd = false;
var ws = document.getElementById('WorkOrderStatusList');//下拉框
var wsold = ws.options[ws.selectedIndex].value;
var At = document.getElementById('AlarmHandleTypeList');//下拉框
var Atold = At.options[At.selectedIndex].value;
var wd = document.getElementById('OrderHandle');//输入框
//At.options[At.selectedIndex].defaultSelectedif (wsold!="")
{
console.log("修改WS");
judjeWs = true;
}
if (Atold != "") {
console.log("修改AT");
judjeAt = true;
}
if (wd.value != wd.defaultValue)
{
console.log("修改Wd");
judjeWd = true;
}
if (judjeWs == true||judjeAt == true||judjeWd == true)
{
return true;
}
else
{
return false;
}
}
2遍历所有的form标签
function JudgesubmitForm() {
var form = document.getElementById('ImgForm');
for (var i = 0; i < form.length; i++) {
var element = form.elements[i];
var type = element.type;
if (type == "checkbox" || type == "radio") {
if (element.checked == element.defaultChecked) {
console.log("没有选择单选或多选框");
}
}
if (type == "hidden" || type == "password" || type == "text" || type == "textarea") {
if (element.value == element.defaultValue) {
console.log("没有进行文本输入");
}
}
if (type == "select-one" || type == "select-multiple") {
for (var j = 0; j < element.options.length; j++) {
if (element.options[j].selected == element.options[j].defaultSelected) {
console.log("没有选择下拉框");
}
}
}
if (type == "file") {
if (element.value.length == 0) {
Filechange = false;
console.log("没选择图片");
}
}
}
