如何取消选中所有 Chromium 复选框

Question

我发现这个代码片段似乎有效，但我尝试实现它并出现了几个错误，我的问题是如何在加载网站后禁用所有复选框。

var filter_form = document.getElementById("filter_form");
var inputs = filter_form.getElementsByTagName("input");
for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].type == "checkbox") {
      /* If default is checked, but state is not checked, check it*/
      if (inputs[i].defaultChecked == true) {
        if (inputs[i].checked != true) {
          inputs[i].checked = true;
        }
      /* If defeault not checked, but state is checked, uncheck it */
      } else {
        if (inputs[i].checked == true) {
          inputs[i].checked = false;
        }
      }
    }  
}
