JavaScript - 查找并替换数组中的单词

Question

如何在数组中找到一个单词(在本例中为占位符，例如 _ORGAN_)并将其替换为元素的值？

sql = new Array();

$('#system').change(function(){
    filter = " topography_index = _ORGAN_";     
    sql.push(filter);
});

在这种情况下，我想将 _ORGAN_ 替换为 $('#organ_menu').val();

Answer 1

试试这个:

// sql array
var sql = ['organ not found', '_ORGAN_ is here'];
var val_to_replace = '_ORGAN_';
var replace_with = 'heart'; // temp value - change it with $('#organ_menu').val()

$.each(sql, function (key, val) {
    // search for value and replace it
    sql[key] = val.replace(val_to_replace, replace_with);
})

console.log(sql)
