Question

我有JavaScript从表单中获取条目，然后在使用“GET”后搜索位置以将这些表单输入应用于值，因为您可以看到它最终与我使用for语句结合很长时间/ else if statement。提高效率的最佳方法是什么？

谢谢！

var search = location.search;
var parts = search.slice(1).split('&');    // Need to slice to remove initial '?'
for (var i=0; i < parts.length; ++i)
{
  var info = parts[i].split('=');
  var variable = info[0];
  var value = info[1];
  if(variable === "pNAME") {

先谢谢你了！

Answer 1

您可以使用变量创建一个对象，并将变量指定为属性将name命名为属性名称。类似的东西：

  var myVar = {};
  for (var i=0; i < parts.length; ++i){
    var info = parts[i].split('=');
    myVar[info[0]] = info[1];
  }

现在，您可以在一个对象中包含所有变量和值，例如myVar.lSS或myVar.pNAME。

Answer 2

把你的pNAME，mAB ......也放在数组中，而不是这样做

function inArray(needle, haystack) {
var length = haystack.length;
for(var i = 0; i < length; i++) {
    if(haystack[i] == needle) return true;
}
return false;

}

否则如果变量分配中的语句效率
