How to search in 2 columns with single search box?

问题

In my project, I would like to find by name and email in the dgrid. As of now, I am able to search by name only. I used the following:

dgrid.set("query", {name: new RegExp(searchKeyword, 'i')});

How do I modify this so that I can search by both, name AND email?

回答1:

The querying engine behind a dojo/store/Memory (called dojo/store/util/SimpleQueryEngine) does not support OR operations, which means it can't query all records where:

name matches searchterm OR email matches searchterm

To solve that issue you will have to use a different query engine than the default one. Currently there are no other query engines available in Dojo but there is a standalone project called the resource query language. You should check this answer and the library itself on Github.

You try to input two parameter in single textbox and want to search result according to that. It is up to you, how you create logic, I tried something hope this will help you.

I have made some alteration in your code so I am explaining what I done only. Here I uesd comma to separate two search value.

var keywordArr = searchKeyword.split(','); // separate search values by comma
var len = keywordArr.length; 
var query = {}; // search object

if(len>1){ // check whether there is two value or single
  query.name = keywordArr[0];
  if(validateEmail(keywordArr[1])){
    query.email = keywordArr[1];
  } 
} else { // if single value then
  if(validateEmail(searchKeyword)){ // check whether is it email or not
    query.email = searchKeyword;                   
  } else {
    query.name = new RegExp(searchKeyword, 'i');
  }                                                                 
}
dgrid.set("query", query); // search query

// function to validate email id
function validateEmail(email) { 
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
        return re.test(email);
}

You can try my code on jsFiddle. Thank you
