[英]How to pass json data from one javascript function to another javascript function?
JS + jQuery + Rails 4
1.)view.html.erb
<%= select_tag "schedule[id]", options_for_select(@travel_names), {:multiple => true, :onchange => "renderSchedules(#{raw @schedule_hash.to_json},#{raw @deals_hash.to_json});" } %>
@schedule_hash =實例,@deals_hash = instance,以json格式傳遞給js函數。
2.)webapp.js
function renderSchedules(json_data, deals_hash){
new_json_data = filterSchedule(json_data, deals_hash);
//More Code
}
function filterSchedule(json_data, deals_hash) {
//More Code
$('#active_fiters_blk').append('<a href="#" id="active_travel_filter" style="color:#F26F21;margin-right:3%;" value="'+operator_ids[i]+'" onclick="removeTravelFilter('+json_data+','+deals_hash+')">"Link"</a>');
// Here i am getting json_data = [object Object], deal_hash = [object, Object] on console , i need to pass json data to removeTravelFilter function
}
function removeTravelFilter(jd, dh){
//Some COnditions
renderSchedules(jd, dh);
// From here also i need to pass json data to renderSchedule function.
}
您需要對json_data
進行字符串化,因為它是一個對象。 對象上的toString
方法返回字符串"[object Object]"
。 您需要使用:
onclick="removeTravelFilter('+JSON.stringify(json_data)+','+JSON.stringify(deals_hash)+')">
您最好不要使用內聯腳本:
function filterSchedule(json_data, deals_hash) {
$('<a href="#" id="active_travel_filter" style="color:#F26F21;margin-right:3%;" value="' + operator_ids[i] + '">Link</a>').on('click', function () {
removeTravelFilter(json_data, deals_hash);
}).appendTo('#active_fiters_blk');
}
也就是說,ID在文檔上下文中必須是唯一的。
看起來您的代碼正在復制ID。
