我需要調用一個rails helper方法並獲取數組的值,以便javascript可以處理它。是否有可能在JavaScript內部調用rails helper?我正在嘗試在我的應用程序中集成jquerys自動完成功能。請找到下面的代碼。內部調用rails輔助方法javascript
$(document).ready(function() {
//**Here the rails helper method will get the list of items**
function split(val) {
return val.split(/,\s*/);
}
function extractLast(term) {
return split(term).pop();
}
$("#tags")
// don't navigate away from the field on tab when selecting an item
.bind("keyup", function (event) {
if (event.keyCode === $.ui.keyCode.TAB && $(this).data("autocomplete").menu.active) {
event.preventDefault();
}
}).autocomplete({
minLength: 0,
source: function (request, response) {
// delegate back to autocomplete, but extract the last term
response($.ui.autocomplete.filter(
availableTags, extractLast(request.term)));
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function (event, ui) {
var terms = split(this.value);
// remove the current input
terms.pop();
// add the selected item
terms.push(ui.item.value);
// add placeholder to get the comma-and-space at the end
terms.push("");
this.value = terms.join(", ");
return false;
}
});
});
我不太瞭解javascript。但是你可以使用這個gem在javascript https://github.com/gazay/gon中獲得你所有的ruby變量 –
