标签： html unicode

HTML是这样的显示文本。我已经检查过了，元字符集已经是... static CTDxf createDxf(boolean fontBold, byte[] fontRGB, byte[] fillRGB) { CTDxf dxf = CTDxf.Factory.newInstance(); CTFont font = dxf.addNewFont(); if (fontBold) font.addNewB(); if (fontRGB != null) font.addNewColor().setRgb(fontRGB); if (fillRGB != null) { CTFill fill = dxf.addNewFill(); fill.addNewPatternFill().addNewBgColor().setRgb(fillRGB); } return dxf; } static void createPivotTableStyle(StylesTable stylesTable, String styleName, Map<STTableStyleType.Enum, CTDxf> typeStyles) { // get or create table styles CTTableStyles tableStyles = stylesTable.getCTStylesheet().getTableStyles(); if (tableStyles == null) tableStyles = stylesTable.getCTStylesheet().addNewTableStyles(); // add table style named as styleName CTTableStyle tableStyle = tableStyles.addNewTableStyle(); tableStyle.setName(styleName); // set TableStyleType styles: TableStyleType -> dxf for (Map.Entry<STTableStyleType.Enum, CTDxf> entry : typeStyles.entrySet()) { STTableStyleType.Enum type = entry.getKey(); CTDxf typeDxf = entry.getValue(); int dxfId = stylesTable.putDxf(typeDxf); CTTableStyleElement tableStyleElement = tableStyle.addNewTableStyleElement(); tableStyleElement.setDxfId(dxfId-1); tableStyleElement.setType(type); } } ... 。我不知道为什么会发生，请帮助:)

我正在这样读取文件，并将其显示在屏幕上。由于meta是utf-8。它应该显示正确，但是没有提示

这是如何使用javascript解析CSV的基本示例。

我没有印地文字符的错误。请注意，所有值都是字符串，您仍然需要将一些值转换为数字并处理{{man1}}双括号中的内容。

const inputElement = document.getElementById("csv");

inputElement.addEventListener("change", handleFile);

function handleFile () {
  let file = this.files[0];
  let fileReader = new FileReader();
  fileReader.onload = handleText;
  fileReader.readAsText(file);
}

function handleText () {
  let lines = this.result.split('\n');
  let headers = lines[0].split(',');
  let parsed = [];
  for (let i=1; i<lines.length; i++) {
    let line = lines[i].split(',');
    let item = {};
    for (let j=0; j<headers.length; j++) {
      item[headers[j]] = line[j];
    }
    parsed.push(item);
  }
  console.log(parsed);
}
<input type="file" id="csv" accept="text/csv">
