Within my default JSON file, I have the following structure:
{
"_name":"__tableframe__top",
"_use-attribute-sets":"common.border__top",
"__prefix":"xsl"
}
My goal is to add values by creating an array, but I am encountering an issue where my array returns undefined after pushing the data.
{
"_name":"__tableframe__top",
"_use-attribute-sets":"common.border__top",
"__prefix":"xsl",
"attribute":[undefined]
}
Initially, I check if the object already contains an array. If not, then I create one. If there's already an array present, no action is taken.
if(!($scope.tObj.stylesheet["attribute-set"][4].attribute instanceof Array)){
const tableframe__top_content = $scope.tObj.stylesheet["attribute-set"][4].attribute;
$scope.tObj.stylesheet["attribute-set"][4].attribute = [tableframe__top_content];
}
Following this, I verify if an attribute with a _name value of something already exists within the array. If it does not, then I proceed with pushing.
var checkTableFrameTopColor = obj => obj._name === 'border-before-color';
var checkTableFrameTopWidth = obj => obj._name === 'border-before-width';
var checkTableFrameTopColor_available = $scope.tObj.stylesheet["attribute-set"][4].attribute.some(checkTableFrameTopColor);
var checkTableFrameTopWidth_available = $scope.tObj.stylesheet["attribute-set"][4].attribute.some(checkTableFrameTopWidth);
if( checkTableFrameTopColor_available === false && checkTableFrameTopWidth_available === false ){
$scope.tObj.stylesheet["attribute-set"][4].attribute.push({
"_name": "border-before-color",
"__prefix": "xsl",
"__text": "black"
},{
"_name": "border-before-width",
"__prefix": "xsl",
"__text": "1pt"
}
);
console.log("pushed successfully");
console.log($scope.tObj);
}
However, I keep getting a null value in the array and encounter an error stating
TypeError: Cannot read property '_name' of undefined at checkTableFrameTopColorWhat am I doing incorrectly?
EDIT:-
This is the desired outcome that I want to achieve-
{
"attribute":[
{"_name":"font-weight","__prefix":"xsl","__text":"bold"},
{"_name":"color","__prefix":"xsl","__text":"black"}
],
"_name":"__tableframe__top",
"_use-attribute-sets":"common.border__top",
"__prefix":"xsl"
}
