问从onclick/onchange事件获取HTML复选框值

EN

handleCheckboxChange(e) {
  console.log('value of checkbox : ', e.target.checked);
}
render() {
  return <input type="checkbox" onChange={this.handleCheckboxChange.bind(this)} />
}

<input type="checkbox" onclick="onClickHandler()" id="box" />

<script>
function onClickHandler(){
    var chk=document.getElementById("box").value;

    //use this value

}
</script>

use onclick event on all checkboxes that you want to get their values whether they are checked or not.

<input type="checkbox" value="rightSideCheckbox" onclick='handleClick(this);'>

function handleClick(checkbox) {
    if(checkbox.checked){
        console.log(checkbox.value+"True")
    }
    else{
        console.log(checkbox.value+"False")
    }
}
