I'm working with BootstrapVue.
I have following problem. I have a b-form-input where I'm searching for my number over my b-form-select. So I'm selecting 3 values and get a number in my input field and other way around - so it's an Autofill.
This works fine - and because of that I think I don't need to show you the code.
The problem is that I want to disable all selects (instead of the first) till the field before was selected.
I have problem that if I have multiple elements all will be updated. So if I input something in Input1 in the first element the second Input of all other elements will be !disabled
Additional Info: IDParent is a prop!
If you need any additional code, I can update my question!
<template>
<div>
<div class="mt-2" v-for="(IDChild, indexChild) in inputs" :key="indexChild">
<div>
<div class="mt-2">Number</div>
<b-form-input type="number" v-model="IDChild.Number" :value="IDChild.Number"></b-form-input>
</div>
<div>
<div class="mt-2">Input 1</div>

this.json.forEach((element) => {

element.Input1 == input.Input1 &&
element.Input2 == input.Input2 &&

) {
for (const key of Object.keys(element)) {
input[key] = element[key];
}
}
});
if(input.Input1) {

disabledInput3: true,
};
},
};
</script>

What you are missing is a multi-layer model for your data which you can call in your searchNumber function and call for your :disabled attribute.
In your v-for="(IDChild, indexChild) in inputs" you could use IDChild or indexChild for that. For example you would call :disabled="disabledInput2[indexChild]". That way you would refer to disabledInput2 with the specific indexChild.
You also need to handle this in your function, for example this.disabledInput2[indexChild] = false;.
Basically it´s the same as storing multi-layer data in the same object with v-model. Let me know, if this helped you.
EDIT: Generally Example
I´ve created the following properties for this example. We have myNumberInput as an object to handle multiple input fields for numbers. mySelectionData provides a simple collection of two objects with 3 selection arrays each. myDisableData is the object that will handle multiple disabled attributes for this selections:
myNumberInput: {},
mySelectionData: {
1: {
1: [
{ name: "1A", value: 1 }, { name: "2A", value: 2 }, { name: "3A", value: 3 }
],
2: [
{ name: "4A", value: 4 }, { name: "5A", value: 5 }, { name: "6A", value: 6 }
],
3: [
{ name: "7A", value: 7 }, { name: "8A", value: 8 }, { name: "9A", value: 9 }
]
},
2: {
1: [
{ name: "1B", value: 11 }, { name: "2B", value: 21 }, { name: "3B", value: 31 }
],
2: [
{ name: "4B", value: 41 }, { name: "5B", value: 51 }, { name: "6B", value: 61 }
],
3: [
{ name: "7B", value: 71 }, { name: "8B", value: 81 }, { name: "9B", value: 91 }
]
}
},
myDisableData: {}
From the mySelectionData object, we will build our myDisableData with this function:
setupMyDisableData() {
Object.keys(this.mySelectionData).forEach(parent_key => {
Object.assign(this.myDisableData, {[parent_key]: {}})
Object.keys(this.mySelectionData[parent_key]).forEach(child_key => {
Object.assign(this.myDisableData[parent_key], {[child_key]: true})
});
});
}
This will loop trough our "parents", assign their index to myDisableData and also loop trough the "childs" and assign their index to myDisableData with the "parent"-index as a pointer. After that we have a multi-layer object which is able to provide diabled= true or false for each selection.
The html for this example looks like this:
<div v-for="(item,index) in mySelectionData" :key="index">
<input type="number" v-model="myNumberInput[index]" @input="enableMySelection(index, myNumberInput[index])">
<div v-for="(child_item, child_index) in item" :key="child_index">
<select :disabled="myDisableData[index][child_index]">
<option v-for="(child_option, child_option_index) in child_item" :key="child_option_index" :value="child_option.value">{{child_option.name}}</option>
</select>
</div>
</div>
As I don´t use BootstrapVue, my html looks different, but I guess you will get the trick. You simply now refer to the three object by the index of "parent" and "child". In this example the function enableMySelection will enable a selection depending on the number entered in the input. The function looks like this:
enableMySelection(parent_index, input_number) {
Object.keys(this.myDisableData[parent_index]).forEach(child_key => {
this.myDisableData[parent_index][child_key] = true;
});
this.myDisableData[parent_index][input_number] = false;
}
So if you enter "2" in your first input, it will enable the second selection of the first block. If you enter 1 in the second input, it will enable the first selection in the second block.
As I said, this is just a generally example but this should be enough to help you define the structure to handle your multiple inputs and selections.
