如何从数组中删除空值。例如

var data = [
    ["George L. Bunting", null, null, null],
    ["Marc G. Bunting", null, null, null],
    ["Suzanne F. Cohen", null, null, null],
    ["Rosalee  Davison", null, null, null],
    ["Richard  Davison", null, null, null],
    ["Marilynn K. Duker", null, null, null],
    ["Dale  McArdle", null, null, null],
    [null, null, null, null],
    [null, null, null, null],
    [null, null, null, null]
]

我要求得到这样的

data = [
    ["George L. Bunting", null, null, null],
    ["Marc G. Bunting", null, null, null],
    ["Suzanne F. Cohen", null, null, null],
    ["Rosalee  Davison", null, null, null],
    ["Richard  Davison", null, null, null],
    ["Marilynn K. Duker", null, null, null],
    ["Dale  McArdle", null, null, null]
]

并删除单词'Dale McArdle'之间的空格 - ＆gt; 'Dale McArdle'？

$("input[id*=btnListGeneratorwithDetails]").click(function() {
    $("[id*=hdnfldSpreadSheetData]").val(JSON.stringify(handsontable.getData()));

    strEntityList = JSON.stringify(handsontable.getData());
    //alert(strEntityList);
});

您可以结合使用.filter和.every：

var data = [
    ["George L. Bunting", null, null, null],
    ["Marc G. Bunting", null, null, null],
    ["Suzanne F. Cohen", null, null, null],
    ["Rosalee  Davison", null, null, null],
    ["Richard  Davison", null, null, null],
    ["Marilynn K. Duker", null, null, null],
    ["Dale  McArdle", null, null, null],
    [null, null, null, null],
    [null, null, null, null],
    [null, null, null, null]
]
data = data.filter(function(entry) {
    return !entry.every(function(value) {
        return value === null;
    });
});
console.log(data);
