Javascript push 方法来填充数组

Question

我想在屏幕上显示 pushIssue 数组，对象 issue 仅在 Javascript 的帮助下被插入数组 pushIssue。据我所知，它可以通过 pushIssue.push(issue) 来完成，然后我尝试使用 document.write() 在屏幕上显示它，但无法显示它

var issue = {
    id: 1,
    description: "This space is for description",
    severity: "This is severity",
    assignedTo: "Name of the assigned person",
    status: "Issue Status "
  }
var pushIssue = [];

将元素插入数组后，您可以使用 JSON.stringify

The JSON.stringify() method converts a JavaScript value to a JSON string, optionally replacing values if a replacer function is specified, or optionally including only the specified properties if a replacer array is specified.

对于 JSON notation 中的字符串化值数组的。

var issue = {
        id: 1,
        description: "This space is for description",
        severity: "This is severity",
        assignedTo: "Name of the assigned person",
        status: "Issue Status "
    },
    issues = [];

issues.push(issue);

document.write('<pre>' + JSON.stringify(issues, 0, 4) + '</pre>');

为了更好的解决方案，因为如果页面已经呈现并且 document.write生成一个新页面，你可以使用 <pre>标记并插入字符串化对象。

var issue = {
        id: 1,
        description: "This space is for description",
        severity: "This is severity",
        assignedTo: "Name of the assigned person",
        status: "Issue Status "
    },
    issues = [];

issues.push(issue);

document.getElementById('out').appendChild(document.createTextNode(JSON.stringify(issues, 0, 4)));

<pre id="out"></pre>
