My JSON document is structured as follows:
{
"X": [
{
"a": "foo",
"b": "bar"
},
{
"a": "xyz",
"b": "cvb"
}
]
}
I have a requirement to retrieve the value of "b" based on the input of "a" in my JavaScript code. For example, if I provide "foo" as input, I should get "bar" as output.
Since I am working with MarkLogic, I am seeking assistance from anyone familiar with this for guidance.
If you're wondering how to accomplish this task, here's one way to go about it:
let obj = {
x : [{
"a":"foo",
"b":"bar"
},
{
"a":"xyz",
"b":"cvb"
}
]
}
passValue = (value) => {
obj.x.forEach(data => {
// iterate through the keys
Object.keys(data).forEach(key => {
// get the value for each key and look if required value has been matched
if(data[key] == value){
if(key == 'a'){
console.log(data['b']);
}else{
console.log(data['a']);
}
}
});
});
}<input type='button' onclick='passValue("foo")' value='pass value foo' />
<input type='button' onclick='passValue("bar")' value='pass value bar' />
<input type='button' onclick='passValue("xyz")' value='pass value xyz' />
<input type='button' onclick='passValue("cvb")' value='pass value cvb' />I am trying to determine the rotation of a specific point in terms of its top and left positions.
