Question

当我执行此功能时，它会显示以下错误：

“JavaScript执行超出超时”我如何通过使用settimeout（）或什么来解决这个问题？

我从json文件中检索3000行。

 applyChanges_PhrasesTypes: function(employees, callback) {

            //alert("fonction apply chamges est lancer PhrasesTypes");

          this.db.transaction(
                function(tx) {
                    var l = employees.length;
                    var sql =
                        "INSERT OR REPLACE INTO PhrasesTypes (IdPhrase, IdPhraseES, IdRubrique, IdTypeTravauxAffichage, Phrase, AidePhrase, AvertissementPhrase,OrdrePhrase,QuotationParDefaut,Published) " +
                        "VALUES (?,?,?,?,?,?,?,?,?,?)";
                    //alert('Inserting or Updating in local database:  PhrasesTypes');
                    var e;
                    for (var i = 0; i < l; i++) 
                    {
                        e = employees[i];
                        log(i);
                        //log("Ligne  "+ i +"  est inserer de id PhrasesTypes = "+e.IdPhrase);
                        var params = [e.IdPhrase, e.IdPhraseES, e.IdRubrique, e.IdTypeTravauxAffichage, e.Phrase, e.AidePhrase, e.AvertissementPhrase,e.OrdrePhrase,e.QuotationParDefaut,e.Published];
                        tx.executeSql(sql, params);
                    }
                    log('sync_PhrasesType shronization terminée avec (' + l + ' items sync_PhrasesTypeshronié)');
                },
                this.txErrorHandler_PhrasesTypes,
                function(tx)
                {
                    callback();
                }
            );
        }

@lgor：这是我的代码，但只有2000插入行，并以错误终止

JavaScript执行超出了超时javascript

 InsertPortion: function(tx)
    {
     var l = Math.min(gEmployees.length, gIter + 300);

     log('aaaaaaaaaaaaaaaaaaaaaaaa---'+l)

     for (; gIter<l ; gIter++)
                {
         log('do insert here'); 
          var sql =
             "INSERT OR REPLACE INTO PhrasesTypes (IdPhrase, IdPhraseES, IdRubrique, IdTypeTravauxAffichage, Phrase, AidePhrase, AvertissementPhrase,OrdrePhrase,QuotationParDefaut,Published) " +
