As per all modern browsers law, that seamlessly not applied to the Microsoft, in indeed for new concepts implemented in the Web world is low migration level of the Internet Explorer in case of basic data interchanges too. The programming world nowadays got stuck with modern data interchange concepts like JSON (JavaScript Object Notation), a data interchange format that's widely used for programming paradigm where get dammed in lower versions of Internet Explorer, an old and well packed browser application developed by Microsoft.
The actual problems of JSON with IE is lies upon the object and its spaces,comma's etc in a programming approach. It completely depends upon the 'null' , 'undefined' and 'NaN' values in a running / flow of our API.
The error triggered while operating over a null/undefined values in IE8
The common problem of IE8 is that of it doesn't extend any new features that cop with modern browsers in a meaningful manner. Like IE8, the older versions treat the values and its behavior in a unpredictable manner in terms of the browser's API. For instance, consider a json file have a mixed format and structure, and also have a splitter array values:
{
"@timestamp": "20140915T054400,50Z",
"@toplevelentries": "15",
"viewentry": [
{
"@position": "1",
"@unid": "045C9DDFDC7AB308C1257C1B002E11F1",
"@noteid": "CEE",
"@siblings": "552",
"entrydata": [
{
"@columnnumber": "2",
"@name": "$14",
"textlist": {
"text": [
{
"0": "Json array testing"
},
{
"0": "test"
}
]
}
}
]
}
}
The result of fetching the "text" field set will result an error because of the structure of array. The array object "0" where allotted two times with a separation of ',' (comma) is treated like a fatal error in IE8 and its lower versions.So it halts the execution of the script.
For fixing such an error, we just need to process the array structure of the JSON file without an ending ',' or removing the replicated object with same object id inside an array (here ,"0" th object).
Filter through a json array (IE8 shut down the service)
For using the filter() function for an Array Prototype in JavaScript will reduce the complexity over high volume data check. The sequential order searching through an array by using filter() function is not supported in IE8 and lower versions.And so, for a perfect usage of map,filter and splice functionalities where dammed with IE8 and its lower cousins.
