Question

我想在触发提交按钮时显示成功消息，但仅在10次某种时间之后，为此我写了以下几行。

  let timeoutId = setTimeout(() => {  
                           this.success = true;;
                            },500);

Simmilarly，我想在一段时间后关闭消息，让我们5秒。任何人都可以建议我怎么做。谢谢。

    /*
    string = {"Canna Terra PLUS 50 Litres", "Canna Vega Tent", "Canna Bio Vega", "Super Canna 50 max" }
    search = "Canna Vega"  this can be dynamic ranging up to 4 words search term

    The expected return array would be

    {"Canna Vega Tent", "Canna Bio Vega" }

    */

    function loadSuggest(string,search){

        if( search.length < 3 ){ 
            return; // suggest is loaded only if the search term is more than 3 letter
        }

        var terms = search.split(' '); // split the search term with spaces
        var i;

        for(i = 0; i < string.length; i++){

            /*
            how to dynamically check and return
            the results containing more than one term match ?
            I have tried indexOf() but that fails with dynamic number of words matching
            */

        }
        return resultArray;
    }

Observable.timer(500).subscribe(() => {
  this.success = true;
  Observable.timer(5000).subscribe(() => this.success = false);
});
