I am exploring how to integrate the jQuery Query Builder into my angular-cli project.
Initially, I attempted to use the plugin from laplasianin/angular-jqueryQueryBuilder, but I struggled with importing it into my component due to lack of clear instructions. My knowledge of angular/typescript is limited.
Subsequently, I tried installing the builder package on my own:
npm install jQuery-QueryBuilder
I included it in my component similar to how you would import jQuery. Below is an example code snippet based on this demo:
import {AfterViewInit, Component} from "@angular/core";
import * as jQuery from "jquery";
import "jQuery-QueryBuilder/dist/js/query-builder.standalone.js";
import "jQuery-QueryBuilder/dist/css/query-builder.default.css";
@Component({
selector: 'app-query-builder',
templateUrl: './query-builder.component.html',
styleUrls: ['./query-builder.component.scss']
})
export class QueryBuilderComponent implements AfterViewInit{
protected rules_basic = {
condition: 'AND',
rules: [{
id: 'price',
operator: 'less',
value: 10.25
}, {
condition: 'OR',
rules: [{
id: 'category',
operator: 'equal',
value: 2
}, {
id: 'category',
operator: 'equal',
value: 1
}]
}]
};
ngAfterViewInit() {
this.getQueryBuilder();
}
private getQueryBuilder() {
let queryBuilder = jQuery.fn.queryBuilder;
jQuery('#builder').queryBuilder({
plugins: ['bt-tooltip-errors'],
filters: [{
id: 'name',
label: 'Name',
type: 'string'
},
// Other filter configurations omitted for brevity
],
rules: this.rules_basic
});
}
}
While the application compiles and loads successfully, I encounter the following error message:
Cannot read property 'template' of undefinedI am struggling to troubleshoot and resolve this issue. Any guidance or assistance would be highly appreciated. Thank you.
