js读取本地文件内容

直接参考以下代码:

<input type="file" onchange="upload(this)"/>

function upload(input) {
  //支持chrome IE10 ff
  if (window.FileReader) {
    var file = input.files[0];
    filename = file.name.split(".")[0];
    var reader = new FileReader();
    reader.onload = function () {
      console.log(this.result);
      alert(this.result);
    };
    reader.readAsText(file);
  }
  //支持IE 7 8 9 10
  else if (typeof window.ActiveXObject != 'undefined') {
    var xmlDoc;
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.load(input.value);
    alert(xmlDoc.xml);
  }
  //支持FF
  else if (document.implementation && document.implementation.createDocument) {
    var xmlDoc;
    xmlDoc = document.implementation.createDocument("", "", null);
    xmlDoc.async = false;
    xmlDoc.load(input.value);
    alert(xmlDoc.xml);
  } else {
    alert('error');
  }
}
