检索表单值以JSON字符串形式发送到localStorage的最简单方法是什么?我用for循环开始了一个函数,但是被卡住了。任何微调都非常感谢(对此还是很新的)请不要使用JQuery。谢谢
<input type="submit" name="submit" value="submitOrder" onclick="return getValues();">
var userOrder='';
function getValues(){
for(var i=0; i < document.forms[0].length - 1; i++){
console.log(document.forms[0][i]);
return false;
}
}
localStorage.setItem('userOrder',JSON.stringify(userOrder));
console.log(localStorage.getItem('userOrder'));
最佳答案
您可以这样做:
html:
<form id="myform">
<input type="text" name="test">
<input type="submit" value="submitOrder">
</form>
js:
const userOrder = {};
function getValues(e) {
// turn form elements object into an array
const elements = Array.prototype.slice.call(e.target.elements);
// go over the array storing input name & value pairs
elements.forEach((el) => {
if (el.type !== "submit") {
userOrder[el.name] = el.value;
}
});
// finally save to localStorage
localStorage.setItem('userOrder', JSON.stringify(userOrder));
}
document.getElementById("myform").addEventListener("submit", getValues);
