ViewsHow to declare a variable in axios get json
I am using axios.get to retrieve the element I want, and it return successfully with json data showen below:
It gooes fine, with [ and { perfectly allocated. Here is my duty, I want to retrieve one column element (this json only has one templete), let's say OrederReferencePreffix, it returns undefined instead of [[\t ... I've try these declaration below:
var attempt_one= json_only[0].InvoiceNumberPreffix; //undefined
var attempt_two= response.data.InvoiceNumberPreffix; //undefined
var attempt_three= response.data[0].InvoiceNumberPreffix; //undefined
var attempt_four= json_only.InvoiceNumberPreffix; //undefined
The php returns the correct one like above, and in js
axios.get('http://localhost/backend/get_templete.php', {
params: {
clciked_cpy: cpy
}
})
.then(function(response) { //attempt above, need to put my ans in here; tried
var json_only = pre_cpy_cut.exec(response.data.toString());
console.log("=]" + json_only);
} #reponse.data
in case you need, php:
$json = array();
while($row = mysqli_fetch_assoc($result)) {
$json[] = $row;
}
mysqli_free_result($result);
echo json_encode( $json, JSON_UNESCAPED_SLASHES ); //return as same as the picture above
#response.data already gives me json and stuff for me already. Why it still not return the column data I want? How to do that.

I think you could gave more informations about your code, but for what I understood you aren't manipulating the JSON correctly. You need to parse the data retrieved by the axios request. Try:
axios.get('http://localhost/backend/get_templete.php', {
params: {
clciked_cpy: cpy
}
})
.then(function(response) {
const parsedResponse = JSON.parse(response.data)
// now you can access correctly the response data.
console.log(parsedResponse.anyVariableYouWant)
})
