How to pass Json string as a javascript method parameter
提问by user2440125
I formed a Json String.
我形成了一个 Json 字符串。
var jsonProduct = "{Product:'" + Details[0] + "',Brand:'" + Details[1] + "',Model:'" + Details[2] + "',Price:'" + Details[3] + "'}"
<input class="button black" type="submit" value="Add To Cart" onclick="return addOrderItem(' + jsonProduct + ')" />
How to pass this 'jsonproduct to javascript function addOrderItem as follows
如何将这个 'jsonproduct 传递给 javascript 函数 addOrderItem，如下所示
function addOrderItem(product)
{
cartproduct[cartproduct.length] = " + product + ";
//cartproduct[cartproduct.length] = " + {Product:'1001',Brand:Dell',Model:'Inspiron',Price:'25000'} + ";
}
When I pass product as parameter it is not working
当我将产品作为参数传递时，它不起作用

You could parse it using
你可以解析它使用
var product = JSON.parse(jsonProduct);
but you don't have to use JSON at all. Do this :
但您根本不必使用 JSON。做这个 ：
var product = {
Product: Details[0], Brand:Details[1],
Model:Details[2], Price:Details[3]
};
addOrderItem(product);
If you want to call this from an input click, you can bind the call using
如果你想从输入点击调用它，你可以使用绑定调用
onclick="return addOrderItem(product)"
or, better, give an id to your element and then bind the event handler from the JS code :
或者，更好的是，为您的元素提供一个 id，然后从 JS 代码绑定事件处理程序：
<input id=submit class="button black" type="submit" value="Add To Cart">
<script>
document.getElementById('submit').onclick=function(){addOrderItem(product)};
</script>
