我已经动态生成了这个复选框元素,我正在尝试动态检查它。
这是我的做法:

var id = "123"; //dynamically generated

var input = document.createElement("input");

input.setAttribute("type", "checkbox");
input.setAttribute("name", "x_"+id);
input.setAttribute("id", "x_"+id);
input.setAttribute("value", "");

input.setAttribute("checked",true);  //This isn't working

var elem = document.getElementById('x_' + id);
elem.checked = true;      //This isn't working

最佳答案

您实际上从未将元素添加到页面中。它在这里工作,只需要做:

document.body.appendChild(input);



var id = "123"
var input = document.createElement("input");

input.setAttribute("type", "checkbox");
input.setAttribute("name", "x_"+id);
input.setAttribute("id", "x_"+id);
input.setAttribute("value", "");

input.setAttribute("checked",true);  //This isn't working

document.body.appendChild(input);

var elem = document.getElementById('x_' + id);
elem.checked = true;      //This isn't working`enter code here`
