i'm a new dev
i'm trying to pass parameter to an onclick function of a button that i've created in JS



dropzone init function look like this :



init: function(){
this.on("addedfile", function() {
if (this.files[1]!=null){
this.removeFile(this.files[0]);
}});
this.on("complete", function () {
previewFileBtn = document.createElement('button');
previewFileBtn.id = "previewFileId";
document.querySelector("#theFile").append(previewFileBtn);
var rt = document.createTextNode("preview the file ");
var name = this.files[0].name;
console.log("name =",name);
previewFileBtn.appendChild(rt);
document.body.appendChild(previewFileBtn);
previewFileBtn.onclick = function (){console.log("preview file Clicked");
window.location.href = "{{ url_for('readpreview', name=name )}}";
}});


var readButton = document.querySelector('#read');
myDzRead = this;
readButton.addEventListener("click",function(){
myDzRead.processQueue();});
}});




python / flask file only had this



@app.route("/readpreview/<name>" , methods=["GET" , "POST"])


def readpreview(name):



print(name)


return render_template('readpreview.html',df=df)


when i click on the button "preview the file"



i get this error rendered (( on http://127.0.0.1:5000/readpreview/ )) not ((http://127.0.0.1:5000/readpreview/ < name >))

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.


and on console



127.0.0.1/:1 Failed to load resource: the server responded with a status of 404 (NOT FOUND)
