我试图将jQuery更改为Vue.js，但在使用vueresource运行Ajax调用时遇到了一些困难。下面是我正在使用的示例脚本，包括jQuery和Vuejs。两者都试图访问相同的Ajax调用。jQuery调用有效，但vuejs调用不起作用，而且，这只会在通过Wordpress运行Ajax调用时导致错误。有什么建议吗？

let AjaxUrl = "http://localhost:8888/mySite/wp-admin/admin-ajax.php";
const postData = { action: 'my_ajaxcall', function: 'AjaxTest' };
Vue.use(VueResource);
const ajax_app = new Vue({
el: '#myvue',
methods: {
sendAjax() {
alert("VueAjax");
alert(JSON.stringify(postData));
this.$http.post(AjaxUrl, postData).then(res => {
alert(JSON.stringify(res));
});
}
}
});
$("#jQueryAjax").click(function() {
alert("jQueryAjax");
alert(JSON.stringify(postData));
alert(AjaxUrl);
$.ajax({
type: 'POST',
url: AjaxUrl,
data: postData,
dataType: 'json',
success: function(data) {
alert(JSON.stringify(data));
},
error: function (xhr, ajaxOptions, thrownError) {
alert("Error");
}
});
});
</script>

You AJAX call probably encounters an error and you handle only the successful calls. Please extend your sendAjax function like this:
this.$http.post(AjaxUrl, postData).then(res => {
alert(JSON.stringify(res));
}, err => {
alert(err);
});
Now an error should be alerted.
BTW: It is better to use console.log() instead of alert(), it is much more readable and you won't have to confirm every alert.
After @mbuechmann pointing me to be able to see the actual error, I was able to determine that the issue I was having was actually to do with Wordpress. In order to use the Wordpress Ajax handler, you need to send an action to the REQUEST header. To do this, you need to send FormData, and without sending headers.
This code was found in this question : Custom Shortcode AJAX 400 Bad Request and enabled me to get my Fetch working with Wordpress.
var data = new FormData();
data.append( 'action', 'aj_ajax_demo' ); data.append( 'nonce', aj_ajax_demo.aj_demo_nonce );
fetch(aj_ajax_demo.ajax_url, {
method: 'POST',
body: data, }).then(response => {
if (response.ok) {
response.json().then(response => {
console.log(response);
});
} });
