将div中的提取数据从Excel转换为查询

Question

下面的代码从csv获取数据，并以text呈现到div ，但正在尝试将其转换为获取excel的query ，然后导入并打印为query

从Excel导入数据时的当前输出
例：

column1','column2','column3','column4')
column1','column2','column3','column4')
column1','column2','column3','column4')
column1','column2','column3','column4')
column1','column2','column3','column4')

预期产量

 ('column1','column2','column3','column4'),
('column1','column2','column3','column4'),
('column1','column2','column3','column4'),
('column1','column2','column3','column4'),
('column1','column2','column3','column4');  

JS小提琴演示

HTML：

<input id = "csv" type = "file" /> 

<div id="result"></div>

JS：

$('#csv').change(function(e) {

  if ((window.FileReader) && (e.target.files != undefined)) {
    var reader = new FileReader();
    reader.onload = function(e) {

      var lineSplit = e.target.result.split("\n");
      var content = [];

      for (var j = 1; j < lineSplit.length; j++) {
        var fourColumnsData = lineSplit[j].split(',').slice(0, 4).join("','");

        content.push(fourColumnsData);

      }
      var fileContent = content.join("')<br/>");
      $('#result').html(fileContent);

    };

    reader.readAsText(e.target.files.item(0));
  }
});

尝试以下

 $('#csv').change(function(e) { if ((window.FileReader) && (e.target.files != undefined)) { var reader = new FileReader(); reader.onload = function(e) { var lineSplit = e.target.result.split("\\n"); var content = []; for (var j = 1; j < lineSplit.length; j++) { if (lineSplit[j].trim().length > 0) { var fourColumnsData = "('" + lineSplit[j].split(',').slice(0, 4).join("','") + "')"; content.push(fourColumnsData); } } var fileContent = content.join(","); $('#result').html(fileContent); }; reader.readAsText(e.target.files.item(0)); } });
