Скачивание Json файла с использованием javascript

/ 27 мая 2020

Это мои json данные, которые я в настоящее время получаю при преобразовании файла xml: 

{"mxGraphModel":{"root":{"mxCell":[{"_id":"0"},{"_id":"1","_parent":"0"},{"mxGeometry":{"_x":"200","_y":"100","_width":"100","_height":"100","_as":"geometry"},"_id":"2","_style":"shape=ellipse","_vertex":"1","_parent":"1"},{"mxGeometry":{"_x":"520","_y":"250","_width":"100","_height":"100","_as":"geometry"},"_id":"3","_style":"shape=triangle","_vertex":"1","_parent":"1"},{"mxGeometry":{"_x":"900","_y":"460","_width":"100","_height":"100","_as":"geometry"},"_id":"4","_style":"shape=cylinder","_vertex":"1","_parent":"1"},{"mxGeometry":{"_x":"310","_y":"450","_width":"100","_height":"100","_as":"geometry"},"_id":"5","_style":"shape=actor","_vertex":"1","_parent":"1"},{"mxGeometry":{"_relative":"1","_as":"geometry"},"_id":"6","_edge":"1","_parent":"1","_source":"2","_target":"3"},{"mxGeometry":{"_relative":"1","_as":"geometry"},"_id":"7","_edge":"1","_parent":"1","_source":"5","_target":"3"},{"mxGeometry":{"_relative":"1","_as":"geometry"},"_id":"8","_edge":"1","_parent":"1","_source":"3","_target":"4"}]}}}

Но когда я загружаю те же данные, что и json, я получаю следующее: 

"{\"mxGraphModel\":{\"root\":{\"mxCell\":[{\"_id\":\"0\"},{\"_id\":\"1\",\"_parent\":\"0\"},{\"mxGeometry\":{\"_x\":\"200\",\"_y\":\"100\",\"_width\":\"100\",\"_height\":\"100\",\"_as\":\"geometry\"},\"_id\":\"2\",\"_style\":\"shape=ellipse\",\"_vertex\":\"1\",\"_parent\":\"1\"},{\"mxGeometry\":{\"_x\":\"520\",\"_y\":\"250\",\"_width\":\"100\",\"_height\":\"100\",\"_as\":\"geometry\"},\"_id\":\"3\",\"_style\":\"shape=triangle\",\"_vertex\":\"1\",\"_parent\":\"1\"},{\"mxGeometry\":{\"_x\":\"900\",\"_y\":\"460\",\"_width\":\"100\",\"_height\":\"100\",\"_as\":\"geometry\"},\"_id\":\"4\",\"_style\":\"shape=cylinder\",\"_vertex\":\"1\",\"_parent\":\"1\"},{\"mxGeometry\":{\"_x\":\"310\",\"_y\":\"450\",\"_width\":\"100\",\"_height\":\"100\",\"_as\":\"geometry\"},\"_id\":\"5\",\"_style\":\"shape=actor\",\"_vertex\":\"1\",\"_parent\":\"1\"},{\"mxGeometry\":{\"_relative\":\"1\",\"_as\":\"geometry\"},\"_id\":\"6\",\"_edge\":\"1\",\"_parent\":\"1\",\"_source\":\"2\",\"_target\":\"3\"},{\"mxGeometry\":{\"_relative\":\"1\",\"_as\":\"geometry\"},\"_id\":\"7\",\"_edge\":\"1\",\"_parent\":\"1\",\"_source\":\"5\",\"_target\":\"3\"},{\"mxGeometry\":{\"_relative\":\"1\",\"_as\":\"geometry\"},\"_id\":\"8\",\"_edge\":\"1\",\"_parent\":\"1\",\"_source\":\"3\",\"_target\":\"4\"}]}}}"

Я обнаружил, что в загруженной версии есть нежелательные символы "\". Код, который я использую для загрузки данных: 

function download(jFile) {
 var text = jFile;
 var result = "data:application/json," + encodeURI(text);
 var a = document.createElement("a");
 a.style = "display: none";
 a.href = result;
 a.download = "flowChartJson.json";
 if (window.navigator.msSaveBlob !== undefined) {
   window.navigator.msSaveBlob(blob, a.download);
 window.URL.revokeObjectURL(result);
   return;
 }
 document.body.appendChild(a);
 requestAnimationFrame(function() {
   a.click();
   window.URL.revokeObjectURL(result);
   document.body.removeChild(a);
 });

}

Где я ошибаюсь?

Заранее благодарим за помощь.
