前台利用ajax进行传送数据 ``` $(function () { $('#submit-btn').click(function (event) { event.preventDefault(); var telephone_input = $('input[name="telephone"]'); var sms_captcha_input = $('input[name="sms_captcha"]'); var username_input = $('input[name="username"]'); var password1_input = $('input[name="password1"]'); var password2_input = $('input[name="password2"]'); var graph_captcha_input = $('input[name="graph_captcha"]'); var telephone = telephone_input.val(); var sms_captcha = sms_captcha_input.val(); var username = username_input.val(); var password1 = password1_input.val(); var password2 = password2_input.val(); var graph_captcha = graph_captcha_input.val(); zlajax.post({ "url":"/signup/", 'data':{ 'telephone':telephone, 'sms_captcha':sms_captcha, 'username':username, 'password1':password1, 'password2':password2, 'graph_captcha':graph_captcha, }, 'success':function (data) { if (data["code"] == 200){ //跳转到首页 window.location = '/'; } else{ zlalert.alertInfo(data["message"]); } }, 'fail':function () { zlalert.alertNetworkError(); }, }); }); }); ```
