Javascript-如何在onclick事件中将数组作为参数传递？

Question

I have an array that I want to pass to a javascript onclick function. I send that array in the onclick event of a button. The onclick function return me [object Object]. Is there a different way to do call that function with the array?

Here My Code:

var data_type= $.parseJSON(data_playtype[1]);//{"1":"apple","2":"orange","23":"berry","8":"grape","9":"mango"}


str1.push('<td><a href="javascript:void(0)" onClick="showABC(\''+data_type+'\')">'Data'</td>');



function showABC(fruit){

    $.each(fruit,function(pid,pt){
        alert(pt);
    });

}

Note, data_type not appear to be Array at js ; data_type appear to be Object

Try utilizing .on() , calling showABC() within click event handler with data_type as parameter.

 var data_playtype = []; data_playtype[1] = JSON.stringify({ "1": "apple", "2": "orange", "23": "berry", "8": "grape", "9": "mango" }); var data_type = $.parseJSON(data_playtype[1]); //{"1":"apple","2":"orange","23":"berry","8":"grape","9":"mango"} var str1 = []; str1.push("<td><a href=javascript:void(0)>Data</a></td>"); function showABC(fruit) { $.each(fruit, function(pid, pt) { alert(pt); }); }; $("table tbody").append(str1).find("a") .on("click", function() { showABC(data_type) });

DEMO

Using inline JS is not a good idea. I would use a data attribute to hold the data as follows:

var data_type = .....;
var link = $('<a/>').data('data_type', data_type).html('Data');
str1.push( $('<td/>').html( link ) );

//event handler
link.on('click', function(e) {
    e.preventDefault();
    var data_type = $(this).data('data_type');
    .....
});

Ref: https://api.jquery.com/data/

.data( key, value )

key

Type: String A string naming the piece of data to set.

value

Type: Anything The new data value; this can be any Javascript type except undefined .
