json对象内的Javascript循环

Question

Want the check for every element in the elements object if it has x and y value in positions , and if not apply some default values for x and y.

Debug_Elements_List:{
"elements":{["001","name"],["002","name"]},
"element_position":{"positions": [{"element_name":"001","x":"60","y":"24"},{"element_name":"002","x":"174","y":"21"}]}
}

Answer 1

Correct your JSON and use forEach loop

 var d = [{ Debug_Elements_List: { "elements": [ ["001", "name"], ["002", "name"] ], "element_position": { "positions": [{ "element_name": "001", "x": "60", "y": "24" }, { "element_name": "002", "x": "174", }] } } }] d.forEach(e => { e.Debug_Elements_List.element_position.positions.forEach(k => { if (!k.hasOwnProperty('x')) kx = 0; if (!k.hasOwnProperty('y')) ky = 0; }) }) console.log(d)
