Kantu (Selenium)：如何将元素推送到现有数组

Question

如何在Kantu中向现有数组添加元素

我执行了以下代码，但name2、length2、namesContent2并不像预期的那样

{
  "Name": "testArrayPush",
  "CreationDate": "2019-8-28",
  "Commands": [
    {
      "Command": "storeEval",
      "Target": "new Array ('cat','dog','fish','dog','?','frog','dog','horse','??elephant')",
      "Value": "names"
    },
    {
      "Command": "storeEval",
      "Target": "storedVars['names'].length",
      "Value": "length"
    },
    {
      "Command": "storeEval",
      "Target": "storedVars['names']",
      "Value": "namesContent"
    },
    {
      "Command": "echo",
      "Target": "array names = ${namesContent}",
      "Value": ""
    },
    {
      "Command": "echo",
      "Target": "array length = ${length}",
      "Value": ""
    },
    {
      "Command": "storeEval",
      "Target": "[storedVars['names'],'Thomas']",
      "Value": "names2"
    },
    {
      "Command": "storeEval",
      "Target": "storedVars['names2'].length",
      "Value": "length2"
    },
    {
      "Command": "storeEval",
      "Target": "storedVars['names2']",
      "Value": "namesContent2"
    },
    {
      "Command": "echo",
      "Target": "array names2 = ${namesContent2}",
      "Value": ""
    },
    {
      "Command": "echo",
      "Target": "array length2 = ${length2}",
      "Value": ""
    }
  ]
}

这就是输出，但我期望得到一个长度为10的新数组

该怎么做呢？

第一个数组是ok的，它的长度为9个元素

我想将几个新元素添加到这个现有数组中(稍后在代码循环中对它们进行循环)。

但是第二个数组只有两个元素，第一个元素是旧的数组，第二个元素是新添加的元素

如何正确对待这一点？

Answer 1

如果希望保持原始数组不变，可以使用concat将新元素推送到旧数组的副本中。

所以

{
  "Command": "storeEval",
  "Target": "[storedVars['names'],'Thomas']",
  "Value": "names2"
}

转到

{
  "Command": "storeEval",
  "Target": "storedVars['names'].concat('Thomas')",
  "Value": "names2"
},

输出：

[info]

Executing:  | storeEval | storedVars['names'].concat('Thomas') | names2 | 

[info]

Executing:  | storeEval | storedVars['names2'].length | length2 | 

[info]

Executing:  | storeEval | storedVars['names2'] | namesContent2 | 

[info]

Executing:  | echo | array names2 = ${namesContent2} |  | 

[echo]

array names2 = cat,dog,fish,dog,?,frog,dog,horse,??elephant,Thomas

[info]

Executing:  | echo | array length2 = ${length2} |  | 

[echo]

array length2 = 10
