Javascript 将global.getelementbyid串联到单个变量中

我可以将3

global.getElementById

语句连接到一个变量中吗。下面是一些代码

var cmbOrgNodeType = global.getElementById('cmbOrgNodeType').options[global.getElementById('cmbOrgNodeType').selectedIndex].value;    
var cmbOrgNodeSubType = global.getElementById('cmbOrgNodeSubType').options[global.getElementById('cmbOrgNodeSubType').selectedIndex].value;    
var cmbOrgNodeComponentType = global.getElementById('cmbOrgNodeComponentType').options[global.getElementById('cmbOrgNodeComponentType').selectedIndex].value;

我想将这三个变量连接成单个变量var

TypeID=？

---

如何将这三个变量的值存储在单个变量中？

要创建所有值的串联字符串：

var TypeID = cmbOrgNodeType + cmbOrgNodeSubType + cmbOrgNodeComponentType;

除非您仍然需要单独访问，否则我将执行以下操作：

TypeID = { 
  cmbOrgNodeType: null, 
  cmbOrgNodeSubType: null, 
  cmbOrgNodeComponentType: null 
}
for(name in TypeID) {
  TypeID[name] = global.getElementById(name).options[global.getElementById(name).selectedIndex].value;
}

---

记住，把它们放在一起存放时，保持干燥是件好事

var nodes = {
 cmbOrgNodeType: global.getElementById('cmbOrgNodeType').options[global.getElementById('cmbOrgNodeType').selectedIndex].value,
 cmbOrgNodeSubType: global.getElementById('cmbOrgNodeSubType').options[global.getElementById('cmbOrgNodeSubType').selectedIndex].value,
 cmbOrgNodeComponentType: global.getElementById('cmbOrgNodeComponentType').options[global.getElementById('cmbOrgNodeComponentType').selectedIndex].value
}

alert(nodes.cmbOrgNodeType)
alert(nodes.cmbOrgNodeSubType)
alert(nodes.cmbOrgNodeComponentType)

---

您可以这样通过在javascript中创建一个对象来实现

var TypeID={}
TypeID.cmbOrgNodeType =cmbOrgNodeType ;
TypeID.cmbOrgNodeSubType =cmbOrgNodeSubType ;
TypeID.cmbOrgNodeComponentType =cmbOrgNodeComponentType ;

如果您愿意，可以这样访问它

 TypeID.cmbOrgNodeType
 TypeID.cmbOrgNodeSubType 
 TypeID.cmbOrgNodeComponentType

---

您可以直接连接字符串：

var type = cmbOrgNodeType + " " + cmbOrgNodeSubType + " " + cmbOrgNodeComponentType;

但是，这将很难从中提取它们的旧值，因此，除非您要输出它们，否则我建议您将它们存储在对象中，以便它可以用作一个变量：

var type = {
    "cmbOrgNodeType": global.getElementById('cmbOrgNodeType').options[global.getElementById('cmbOrgNodeType').selectedIndex].value,
    "cmbOrgNodeSubType": global.getElementById('cmbOrgNodeSubType').options[global.getElementById('cmbOrgNodeSubType').selectedIndex].value,
    "cmbOrgNodeComponentType": global.getElementById('cmbOrgNodeComponentType').options[global.getElementById('cmbOrgNodeComponentType').selectedIndex].value
}

（这是）

然后，您可以使用

type.cmbOrgNodeType

等访问每个属性
