reactjs - How can I throttle the setState in React? -


  1. there's searchbar component change whole component state, whole re-render leads child component playerlistwithquery re-render new state well.

  2. there's playerlistwithquery component query graphql server base on search content passed component

the problem don't wanna execute query have change value of input instantly, how can solve issue.

import playerlistwithquery './playerlistwithquery.js' class whole extends component {   constructor(props) {     super(props);     this.state = {       searchcontent: '',     };   }   handlechange = val => {     this.setstate({       searchcontent: val,     });   };    render() {     return (       <div>         <searchbar           placeholder="id"           onchange={this.handlechange}           value={this.state.searchcontent}         />         <playerlistwithquery searchcontent={this.state.searchcontent} {...this.props} />       </div>     );   } }  export default whole;

// playerlistwithquery.js

const playerlistwithquery = graphql(query_single_player, {   options: props => ({     fetchpolicy: 'network-only',     variables: {       id: props.searchcontent,     },   }), })(playerlist);  export default playerlistwithquery;

i using lodash's debounce same thing. or can implement debounce function (credit)

// returns function, that, long continues invoked, not  // triggered. function called after stops being called  // n milliseconds. if `immediate` passed, trigger function on  // leading edge, instead of trailing.  function debounce(func, wait, immediate) {  	var timeout;  	return function() {  		var context = this, args = arguments;  		var later = function() {  			timeout = null;  			if (!immediate) func.apply(context, args);  		};  		var callnow = immediate && !timeout;  		cleartimeout(timeout);  		timeout = settimeout(later, wait);  		if (callnow) func.apply(context, args);  	};  };

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
