When I'm sending state of the child component to its parent component, React is sending old state to the parent component.
I want to send the updated state on every click on ListItem which is properly working and calling the function handleItemClick.
But when I'm calling sendStateToParent
. It is passing old state of it. Suppose I have clicked on ITEM1
, it is sending empty array[]
. Next I have clicked on ITEM2
, it is sending array [ITEM1]
.
Here I'm actually creating a multiselect dropdown. which also can act as single select based on props it is getting.
import React from 'react';
import ListItemComponent from './ListItem.jsx';
import DropDownButtonComponent from './DropDownButton.jsx';
import DropDownStyle from '../../../../css/sass/drop-down.scss';
module.exports = React.createClass({
handleClick: function () {
this.setState({open: !this.state.open});
},
getInitialState: function () {
return {
open: false,
//listItems: this.props.listItems,
selectedItems:[],
title: this.props.dropdownTitle
}
},
handleItemClick: function (item) {
var selectedItems = [];
if(this.props.multiple == true){
selectedItems = this.state.selectedItems;
if(selectedItems.indexOf(item)==-1){
selectedItems.push(item);
}else{
selectedItems.splice(selectedItems.indexOf(item),1)
}
this.setState({
title: this.state.selectedItems.length+" selected",
selectedItems: selectedItems
});
} else{
selectedItems = [];
selectedItems.push(item);
this.setState({
title: item,
selectedItems: selectedItems,
open: false
});
}
this.sendStateToParent();
},
sendStateToParent: function(){
this.props.ifListChanged(this);
},
handleTextChange: function (event) {
var filteredItems = [];
this.props.listItems.map(function(item){
if(item.toLowerCase().search(event.target.value.toLowerCase()) != -1){
filteredItems.push(item);
}
},this);
this.setState({
listItems: filteredItems
});
},
clearSelected: function(){
this.setState({
title: this.props.dropdownTitle,
selectedItems: [],
});
},
render: function () {
var index = 0;
var list=[];
if (this.state.listItems != undefined) {
list = this.state.listItems.map(function (item) {
return (
<ListItemComponent
key={index++}
item={item}
whenItemClicked={this.handleItemClick}
className={this.state.selectedItems.indexOf(item) != -1 ? "active" : ""}
/>);
}.bind(this));
} else {
list = this.props.listItems.map(function (item) {
return (
<ListItemComponent
key={index++}
item={item}
whenItemClicked={this.handleItemClick}
className={this.state.selectedItems.indexOf(item) != -1 ? "active" : ""}
/>);
}.bind(this));
}
return <div className="btn-group bootstrap-select form-control">
<DropDownButtonComponent
whenClicked={this.handleClick}
title={this.state.title}
/>
<ul className={"dropdown-menu inner dropdown-menu " + (this.state.open ? "show" : "") }>
{this.props.search? <li><input type="text" style={{margin:"auto", maxWidth:"96%"}} onChange={this.handleTextChange} placeholder="Search"/></li> :""}
<li className="disabled"><a>Select from below list {this.props.multiple ? <i title="clear all" style={{fontSize:"15px"}} onClick={this.clearSelected} className="text-danger fa fa-ban pull-right"></i>: ""}</a></li>
{list}
</ul>
</div>
}
});
Thanks in advance
