I have an Array of Object to be used to draw a HTML Table:
Array(5)
0: Object
id: 4
name: Sand Jane
address: Green Sand Street
...
...
...
1: Object
2: Object
...
...
...
I am able to do a single name
column defined search with
const temp = this.temp.filter(function (d) {
return d.name.toLowerCase().indexOf(val) !== -1 || !val;
});
temp
will contain the filtered data of this.temp
Now I just can't figure out how to loop through all object keys (id,name,address...) so that I can do a global column search in the Table.
UPDATE : I have tried this,
const temp = [];
this.temp.forEach(element => {
for (let key in element) {
if (element.hasOwnProperty(key)) {
let v = element[key];
if (v.toString().toLowerCase().indexOf(val) !== -1 || !val) {
temp.push(element);
}
}
}
});
It works but with performance issues.
RESOLVED: Putting a break
after temp.push
fixed this issue. Thank you all for the guidelines and references.
temp.forEach(item=>{
for(let key in item) {
//item[key] gives you access to each value
}
})
You can iterate through for loops or even you can usefor loop inside a for loop. Either way it's self explanatory.
var dictionary = {
"employee1":[
{"id":"0","name":"Google"},
{"id":"1","name":"eBay"}
],
"employee2": [
{"id":"2","name":"Yahoo"},
{"id":"3","name":"Facebook"}
]
};
var employee1 = dictionary.employee1;
var employee2 = dictionary.employee2;
for ( var i in employee1) {
var id = employee1[i].id;
var name = employee1[i].name;
console.log(id);
console.log(name);
}
for ( var i in employee2) {
var id = employee2[i].id;
var name = employee2[i].name;
console.log(id);
console.log(name);
}
