Give a phone number that input to perform js assignment document. The getElementById (' user - mobile). Value='https://bbs.csdn.net/topics/15888888888';
And then manually trigger events the blur, change and so on, all have no effect
Send button is always gray, and by looking at the table elements, does not modify the value of real value, consult everybody what reason, how to implement?

CodePudding user response:

Family form is onchange event, it is in your input to change state at the same time, direct assignment must be useless and onchange listener input box to see if there is value, there is value the disable button are removed, no value is automatically and disable is grey

Is how to write your own, through the blur and change event to change the verification code inside of disabled attributes can
Var a=document. GetElementById (' code - the button).
A. d. isabled=false;
Natural color display
Their try to know more, or stick your code, how do you do, do not come out to others can help you, you said you have triggered the doesn't mean you are right, put the code out to see what's the problem

Thanks for your reply, you this method tried, I can't, all the following code
Document. The getElementById (' user - mobile). Value='https://bbs.csdn.net/topics/15888888888';
Var evt=document. CreateEvent (' HTMLEvents'); Evt. InitEvent (' blur ', true, true); Document. The getElementById (' user - mobile). DispatchEvent (evt).
Var evt=document. CreateEvent (' HTMLEvents'); Evt. InitEvent (' change ', true, true); Document. The getElementById (' user - mobile). DispatchEvent (evt).
Var evt=document. CreateEvent (' HTMLEvents'); Evt. InitEvent (" input ", true, true); Document. The getElementById (' user - mobile). DispatchEvent (evt).
Var a=document. GetElementById (' code - the button).
A. d. isabled=false;

This button point may be related to verification, the input number listening, when you enter does not meet the conditions out tips, meet the conditions of the time he will together with some other parameters, if does not meet the conditions were not allowed to request, just like we normally request, click edit to modify a form data, to accompany the data id, if the judge, don't send the request without this id

Question is manual input is no problem, you can point input 1

CodePudding user response:

Enter 1 can do check points, only have give you some value, basic digits check, cell phone number to reach 11 requests the backend will also have a phone number check, enter 1 click on the verification is not successful to send request, input full 11 digits can send the request, but the backend will check,
You don't have to struggle can he avoid, he is a check to meet the conditions for you to generate some data on an object, and is allowed to submit, your hand throw up did not trigger his data generated content, so click no effect
