<input type="checkbox" name="test_checkbox" :checked1111="test" @click="onClick"> TestonClick: function (e) {
this.test = e.target.checked
console.log(this.test)

or written as
<input type="checkbox" name="test_checkbox" :aaafc="test" @click="onClick"> Testcan realize two-way binding of data test

Because what works is your onClick processing function, you bind whether checked to test in this function, so it is okay if you do not write: checked="test" on the input tag.
