如何从jsgrid数据制作一个csv文件

Question

我有一个 jsgrid table，其中包含来自 mysql 的数据。我想从我过滤的数据中制作一个 csv（或其他东西）。我该怎么做。

我找到了这样的东西：

var csv = $("#grid").jsGrid("exportData", {
    type: "csv", //Only CSV supported
    subset: "all" | "visible", //Visible will only output the currently displayed page
    delimiter: "|", //If using csv, the character to seperate fields
    includeHeaders: true, //Include header row in output
    encapsulate: true, //Surround each field with qoutation marks; needed for some systems
    newline: "\r\n", //Newline character to use

    //Takes each item and returns true if it should be included in output.
    //Executed only on the records within the given subset above.
    filter: function(item){return true},

    //Transformations are a way to modify the display value of the output.
    //Provide a key of the field name, and a function that takes the current value.
    transformations: {
        "Married": function(value){
            if (value === true)
                return "Yes"
            if (value !== false)
                return "No"
        }
    }
});

如何从这个变量创建文件？

你可以将数据保存在一个数组中，然后使用这个函数。

function JSONToCSVConvertor(JSONData, Label, ShowLabel) {
    //If JSONData is not an object then JSON.parse will parse the JSON string in an Object
    var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
    var CSV = '';
    //Set Report title in first row or line
    CSV += Label + '\r\n\n';
    //This condition will generate the Label/Header
    if (ShowLabel) {
        var row = "";
        //This loop will extract the label from 1st index of on array
        for (var index in arrData[0]) {
            //Now convert each value to string and comma-seprated
            row += index + ',';

        }
        row = row.slice(0, -1);
        //append Label row with line break
        CSV += row + '\r\n';
    }
    //1st loop is to extract each row
    for (var i = 0; i < arrData.length; i++) {
        var row = "";
        //2nd loop will extract each column and convert it in string comma-seprated
        for (var index in arrData[i]) {

            row += '"' + arrData[i][index] + '",';

        }
        row.slice(0, row.length - 1);
        //add a line break after each row
        CSV += row + '\r\n';
    }
    if (CSV == '') {
        alert("Invalid data");
        return;
    }
    //Generate a file name
    var fileName = "FileTitle";

    //Initialize file format you want csv or xls
    var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);
    //alert(uri);
    // Now the little tricky part.
    // you can use either>> window.open(uri);
    // but this will not work in some browsers
    // or you will not get the correct file extension
    //this trick will generate a temp <a /> tag
    var link = document.createElement("a");
    link.href = URL.createObjectURL(new Blob([CSV], { type: "application/octet-stream" })); //added to fix network error problem in chrome
    //set the visibility hidden so it will not effect on your web-layout
    link.style = "visibility:hidden";
    link.download = fileName + ".csv";
    //this part will append the anchor tag and remove it after automatic click
    document.body.appendChild(link);
    link.click();
    // document.body.removeChild(link);
}
