向 vue.js 中动态创建的表添加按钮

Question

I am trying to dynamically create buttons which are displayed in the 5th (last) column of a table, which is also created dynamically. Everything is created properly. However, upon clicking the buttons, the function is not triggered. Perhaps it is because I am using vue.js to develop my front-end. I have tried using "v-on:click" instead of "click" in the button.setAttribute('click', 'claim()') code below, but this did not help.

  var table = document.createElement('table')
  for (var i = 1; i <= 5; i++) {
    var th = document.createElement('th')
    th.appendChild(header)
    table.appendChild(th)
  for (var j = 1; j <= 4; j++) {
    var tr = document.createElement('tr')
    for (var k = 1; k <= 5; k++) {
      var td = document.createElement('td')
      var node = document.createTextNode(k)
      td.appendChild(node)
      tr.appendChild(td)
      if (k === 5) {
        var button = document.createElement('input')
        button.setAttribute('type', 'submit')
        button.setAttribute('value', 'Purchase')
        button.setAttribute('click', 'purchase()')
        td.appendChild(button)
      }
    }
    table.appendChild(tr)
  }

You need to use addEventListener for adding any event. Example : button.addEventListener('click', purchase)

 var app = document.getElementById("app"); var table = document.createElement('table'); app.appendChild(table) for (var i = 1; i <= 5; i++) { var th = document.createElement('th') //th.appendChild(header) table.appendChild(th) for (var j = 1; j <= 4; j++) { var tr = document.createElement('tr') for (var k = 1; k <= 5; k++) { var td = document.createElement('td') var node = document.createTextNode(k) td.appendChild(node) tr.appendChild(td) if (k === 5) { var button = document.createElement('input') button.setAttribute('type', 'submit') button.setAttribute('value', 'Purchase') button.addEventListener('click', purchase) td.appendChild(button) } } table.appendChild(tr) } } function purchase() { console.log("done") }
