I want to disable an input field, but when I submit the form it should still pass the value.

You can use the readonlyproperty in your input field
您可以readonly在输入字段中使用该属性
<input type="text" readonly="readonly" />

I know this is old but I just ran into this problem and none of the answers are suitable. nickf's solution works but it requires javascript. The best way is to disable the field and still pass the value is to use a hidden input field to pass the value to the form. For example,
我知道这很旧，但我刚刚遇到了这个问题，但没有一个答案是合适的。nickf 的解决方案有效，但它需要 javascript。最好的方法是禁用该字段并仍然传递值是使用隐藏的输入字段将值传递给表单。例如，
<input type="text" value="22.2222" disabled="disabled" />
<input type="hidden" name="lat" value="22.2222" />
This way the value is passed but the user sees the greyed out field. The readonly attribute does not gray it out.
通过这种方式传递值，但用户会看到灰色的字段。readonly 属性不会使其变灰。

you can also use the Readonly attribute: the input is not gonna be grayed but it won't be editable
您还可以使用 Readonly 属性：输入不会变灰但不可编辑
<input type="text" name="lat" value="22.2222" readonly="readonly" />

Input elements have a property called disabled. When the form submits, just run some code like this:
输入元素有一个名为 的属性disabled。当表单提交时，只需运行一些这样的代码：
var myInput = document.getElementById('myInput');
myInput.disabled = true;
